Inventory is an unavoidable problem for e-commerce companies, and it is also the life door for e-commerce companies. Problems in supply chain management are often reflected in inventory, either too much inventory leads to slow sales or too little inventory leads to out of stock.

Inventory management, as its name implies, is to manage the quantity of goods. In general, we can divide it into sales inventory and warehouse inventory.

Sales inventory can also be called foreground inventory, which is the inventory quantity facing the user’s latitude.

Warehouse inventory, which can also be called background inventory, is the inventory quantity oriented to warehouse latitude.

Sales inventory and warehouse inventory, the specific details of which we will introduce in later articles.

The most important behaviors that affect warehouse inventory are warehousing and warehousing.

Warehousing refers to how many commodities have been added, such as purchase warehousing, return warehousing, transfer warehousing, production warehousing, inventory warehousing and other warehousing.

Issue refers to how many commodities have been reduced. Common issues include sales issue, purchase return issue, transfer issue, inventory loss issue and other issues.

In order to better explain the contents of goods in and out of the warehouse (inventory management), according to the process, we will first introduce the basic business in the warehouse, including location introduction, allocation business and inventory business.

In order to better manage the goods, warehouses are generally divided into one cargo space. In this way, every time the goods are put into storage, they will be associated with a location, and when the goods are put out of storage, the location of the goods will be associated with the sorting list, so that the warehouse staff can find the location of the goods quickly and efficiently when distributing the goods.

Here is a way to allocate the cargo space, which also provides an idea:

The above picture is a simple plan of the distribution area, which can be divided into several rows. Each row is named A, B, C, D, E, F, G and H, and each row has many shelves. Combined with the naming of each row, we name each shelf A01, A02, A03, A04, A05 and A06.

The above picture shows a simple shelf. This shelf is named A01, which can be divided into four floors. Each floor is named A01-1, A01-2, A01-3 and A01-4. For each cargo space, we name it A01-1-01, A01-1-02 and A01-1-03.

(1) List of cargo positions

The prototype is relatively simple, so I don’t need to describe it too much here. It is just a configuration page and a display list page, which contains the most basic information such as warehouse, location and status.

Transfer is mainly used to adjust the inventory quantity in the warehouse. Putting the right goods in the right warehouse/location can be divided into intra-warehouse transfer and inter-warehouse transfer.

Intra-warehouse transfer: it can also be called location inventory transfer, which is generally the adjustment of the internal inventory of the warehouse. For example, the goods are transferred from the goods with sufficient inventory to the goods with insufficient inventory, which is convenient for picking goods and managing the inventory of the goods.

Inter-warehouse transfer: it can also be called warehouse inventory transfer, which is generally the adjustment of inventory between warehouses. For example, goods are transferred from Hangzhou warehouse to Shanghai warehouse.

The flow of transfer business mainly revolves around the transfer of transfer documents, involving business personnel, transfer-out warehouse and transfer-in warehouse, from the creation of transfer documents by business personnel to the creation of transfer issue documents by transfer information transfer to transfer-out warehouse, and then to the creation of transfer receipt documents by transfer information transfer to transfer-in warehouse.

(1) business personnel, according to the actual demand to create a transfer form, and submit it for approval.

(2) Relevant personnel review the transfer form. If the review fails, they need to re-edit and submit it.

(3) Transfer out the warehouse, and create a transfer issue document according to the approved transfer document. Of course, the transfer issue document can also select one or several commodities in the transfer document according to the actual situation, and fill in the actual issue quantity.

(4) Transfer to the warehouse, create a transfer receipt document according to the transfer document and the issue document, and do the warehousing operation according to the actual situation.

(5) Expenses incurred in the process of financial settlement and allocation

(1) Transfer billing

Transfer billing is the first step of transfer business in the system. First, you need to select the most basic transfer-out warehouse and transfer-in warehouse, and then select the goods that need to be transferred, and the goods will reach sku latitude. The system will calculate the quantity of goods that can be transferred according to the rules (the specific calculation method of the quantity that can be transferred will be introduced later when we introduce the inventory details), maintain the actual quantity of goods transferred this time, and select the transfer-in location (the transfer-in location will read the location information of the corresponding warehouse according to the basic information).

(2) Transfer Sheet Management

All transfer documents are displayed here. Transfer documents need to be approved here before subsequent transfer-out and transfer-in operations can be carried out.

Status of transfer document:

• Being Edited: equivalent to the draft status, the transfer document can be modified and then submitted for approval.
• Canceled: the document is cancelled, which means the document has been voided.
• Pending approval: the transfer application has been submitted, but it has not been approved.
• Approved: the transfer application has passed, and you can issue it.
• Pending issue: the transfer issue document has been generated, but it has not been approved.
• Partial issue: some goods in the transfer document have been issued.
• Issued: all goods in the transfer document have been issued.
• Pending receipt: the transfer receipt document has been generated, but it has not been approved.
• Partial receipt: some goods in the transfer document have been received.
• Completed: all the goods in the transfer document have been received.

Inventory refers to the total or partial inventory of the physical inventory in the warehouse, so as to truly grasp the goods status during the period, and thus improve and strengthen management.

General invoicing systems provide strict warehousing management, so theoretically, the inventory quantity of the system is consistent with the actual inventory quantity of the warehouse. However, in actual operation, it is inevitable that there will be mistakes and omissions in delivery, or that the process will not be followed. At this time, there will be a mismatch between the theoretical inventory and the actual inventory in the warehouse.

After counting, if the actual inventory data is inconsistent with the theoretical inventory data, an inventory gain receipt document and an inventory loss issue document will be automatically generated to adjust the inventory quantity. Regular inventory not only ensures the accuracy of inventory data, avoids oversold and other phenomena, but also can grasp the problems in inventory operation in time.

Regular inventory not only ensures the accuracy of inventory data, but also can grasp the problems in inventory operation in time and avoid oversold. After counting, if the inventory data are inconsistent, an inventory profit and loss sheet will be generated. The seller can check the inventory changes in the inventory management interface or check the inventory ledger to check what links caused the inventory inaccuracy.

The business mainly focuses on the circulation of inventory sheets, starting from the creation of inventory sheets by business parties, entering inventory, and automatically generating inventory gain receipt documents and inventory loss issue documents to correct the inventory after the inventory is completed.

(1) business personnel, according to the actual demand to create inventory list, and submit it for review.

(2) Relevant personnel shall review the inventory list. If the review fails, it needs to be re-edited and submitted.

(3) the warehouse personnel, according to the inventory list for inventory entry of goods, enter the actual inventory quantity.

(4) According to the comparison between the counting quantity and the inventory quantity, an inventory gain receipt document and an inventory loss issue document are generated.

(5) Relevant personnel review the inventory gain receipt document and inventory loss issue document (if the inventory document personnel are the reviewers, they can be directly approved by default), so as to correct the inventory.

(1) Inventory billing

Inventory billing is the first step of inventory operation, and our inventory process starts here. Inventory billing is mainly used to select inventory warehouse, inventory goods and other information. After clicking Save/Submit for approval, inventory sheets can be generated, and the generated inventory documents can be displayed in the inventory sheet management interface.

(2) Inventory sheet management

It is mainly used to query and manage the inventory list, where we can review the inventory list, enter the inventory and other operations.

Inventory sheet status:

• Being Edited: equivalent to the draft status, the inventory list can be modified and then submitted for approval.
• Canceled: the document is cancelled, which means the document has been voided.
• Pending approval: the inventory application has been submitted, but it has not been approved.
• To be counted: the counting application has been approved, but it has not been entered yet. You can enter the counting sheet.
• Completed: the inventory entry is completed and the inventory is finished.

(3) Inventory entry

This is mainly used to enter the real quantity of goods in the inventory list. After the inventory is completed, the business personnel fill in the actual inventory quantity. After saving, the inventory entry process is completed, and the system will follow the new and original inventory data. If the input quantity is inconsistent with the inventory quantity, the system will automatically generate an inventory gain receipt document and an inventory loss issue document.

This paper mainly introduces the basic business in the warehouse, including location introduction, transfer business and inventory counting business. The following articles will introduce the warehousing management and warehousing management that directly affect inventory data. Finally, the details of sales inventory for user latitude and warehouse inventory for warehouse latitude will be introduced as a whole. Welcome all interested parties to communicate together.

Behind the flood of "Little Yellow Man" in the comment area is a hidden illegal drainage industry chain.

People who regularly brush Weibo may have this worry: in social software such as Weibo, WeChat and QQ, many "movie sellers" drain illegal websites by commenting, paying attention and sending private messages, and the indecent content they send has become "psoriasis" in the online world.

Nowadays, the behavior of "selling movies" has been restricted.

After the rectification in Weibo, the crackdown on internet piracy was even more severe. On June 12th, Weibo set a rule of paying attention to seven days before commenting, and said that this measure was aimed at cracking down on illegal websites and conducting illegal content related to pornographic video transactions. This has limited some users’ experience, and also made some publishers of illegal advertisements selling films and medicines by inducing words in popular Weibo comments lose an important drainage place.

With the attack of various platforms on this kind of advertising behavior, the means of "selling film brothers" are constantly being refurbished, and the victims of these malicious drainage behaviors are often ordinary users who want to clean up the network environment and curious minors who are ignorant of the world.

A survey by the Beijing News Shell Finance reporter found that behind the flood of "Little Yellow Man" in the comment area, there is a hidden illegal drainage industry chain. After the review in the comment area is becoming stricter, such malicious drainage behavior may also appear behind the private letters, concerns and even praises of ordinary users.

"The drainage industry is actually a marketing black product, which is characterized by making extensive use of the identity information of normal citizens, bypassing the platform restriction rules, sending a large number of drainage contents such as pornography, politics and vulgar advertisements, and finally realizing them in the form of fraud." Li You (a pseudonym), an expert in anti-fraud lab, told the reporter.

After the "selling films" in the comment area was severely punished, the censorship was evaded by means of "building in the middle of the building"

"Think about it, why are you being targeted by film sellers?" This sentence used to be a sentence that netizens often teased in Weibo’s comments, but once the comment area was really flooded with all kinds of pornographic comments, most netizens would feel uncomfortable.

Netizen "Ginger Ginger Ginger" sent a complaint to Weibo in May, saying that his Weibo was "targeted by pornography" and posted many malicious comments in his comment area. Many netizens said that these movie sellers were "everywhere". As long as Weibo has traffic on the hot search, the comment area will often attract such drainage comments.

The reporter found that many porn reviews use keywords such as "father-in-law’s daughter-in-law" and "long-legged green tea biao" to attract users to click. After clicking, they often jump to pornographic websites and ask users to pay.

At present, although Weibo strictly controls comments in the comment area, many "film sellers" can still take advantage of the loopholes.

On June 27th, Shell Finance reporter of the Beijing News found the trace of "selling films" in a popular Weibo comment area, but its method of "selling films" became quite complicated: firstly, it did not comment directly under the popular Weibo, but replied in the top comments in the popular Weibo comment area, which belonged to "comments in comments", and the comment content was a picture of a semi-naked beauty with the words: the original picture was at @XXX. The reporter clicked on the Weibo user of this comment @, and found that there were large-scale pornographic pictures on his homepage, with a website link attached. Clicking on the website link found that he jumped to a "movie selling" website, indicating that 28 yuan could buy pornographic movies, and provided the payment method of Alipay. At this point, the process of draining to pornographic websites through Weibo comment area is completed.

The reporter of Shell Finance found that, influenced by Weibo’s "strike hard" pornographic comments, the "movie seller" could only comment on the published comments, and the drainage was realized in the form of "building in the building". The process was more tortuous than the previous direct reply to indecent comments in hot search, which increased the cost of malicious drainage, but it also showed that no matter how the platform was banned, violators could always find ways to counter the ban rules of the platform.

"The platform and malicious drainage of black products are in the process of dynamic confrontation." Li You told the reporter, "If the rules are too strict, it will be deleted by mistake, which will affect the user’s experience. It is unrealistic to completely ban the drainage of gray and black products, unless everyone can’t comment. However, if the rules are relaxed, they will be invaded by gray-black products, and they can only gradually increase the drainage cost of gray-black products, so that they can retreat. "

Comments and private messages frequently show toner drainage "robots", and the price ranges from 1 yuan to 388 yuan

Weibo is not the only battlefield for film sellers. Many social apps, such as QQ, WeChat, Momo, Tik Tok, etc., are active places for these movie sellers.

Some netizens reported that there are always comments from strange users in their comments posted on QQ, and the comments are usually random words, but if you click on the portrait of the strange user, it is usually "a hole in the sky".

On June 23rd, Shell Finance reporter clicked on the comment of a QQ user who "looked at my head first", and found that if he entered the user’s space, he would jump to the document analysis page of Tencent weiyun, but the document content only had a picture with a QR code. If he scanned it, he would jump to another picture with a QR code and explicit content, and then he would jump to a pornographic website. If he wanted to watch the website video, he would have to pay a fee of 6 to 25 yuan.

A black production studio, which claims to provide "toner drainage on all platforms", said that it can provide drainage service at the price of one person in 2 yuan, but only on the micro signal provided by reporters. "If the direct website address is easy to be blocked, we will first drain the fans to your micro-signal or QQ number through words, and then drain them by sending private messages."

Shell Finance reporter found that almost all of these drainage studios use machine scripts to send private messages in batches. On June 26th, the reporter found a number of "studios" engaged in drainage services by searching for related keywords, and some studios also sold scripts of "drainage robots" part-time. These scripts involved many platforms such as WeChat, Weibo, QQ, Toutiao, Tik Tok, Momo, 58 Tongcheng, Jiji.com, Meipai and Soul, and the prices ranged from 1 yuan (single platform) to 388 yuan (multi-platform package price).

For investigation, the reporter bought a set of "customized drainage scripts" from a merchant at a price of 35.2 yuan, including 22 platforms including Himalayan, WeChat, Tik Tok, Meipai, Weibo and Tantan. After opening the script, the reporter found that its "function settings" include seven functions: video comment, fan private message, fan attention, comment private message, comment concern, comment praise and friend private message. On this page, users can manually input comment speech and private message speech, in addition, they can also make routine settings such as sending pictures, repeating sending, adding attention, and double-talk speech, and can also screen men and women.

In this regard, Fang Chaoqiang, a lawyer of Beijing Yingke (Hangzhou) Law Firm, told the Beijing News reporter that the behavior of diverting users from different platforms to micro-signals through speech induction involves at least false advertisements. "If this behavior is ultimately sold as legitimate goods, it is suspected that marketing methods are illegal. After all, this is a false advertisement. If you sell obscene articles or commit fraud, then those who provide drainage services should also be arrested as accomplices, because even if it is only a commercial entrustment relationship, it also provides business cooperation, which plays a role or even a major role in the spread of obscene articles. "

How to manage the malicious external chain after jumping against the platform ban for many times?

Shell Finance reporter noticed that whether it is comments, private letters or concerns, the inevitable process of draining from a formal social platform to an illegal website is to jump to the outside chain, which often becomes the key place for the platform to attack, so many black and gray products do not hesitate to fight against the ban by jumping many times. As mentioned above, the whole process of draining to an illegal website through QQ avatar jumped three times before "getting into the business".

"There is no way to do this." In an exchange forum of black and gray products on the external network, a practitioner of black and gray products said, "In the early days, H5 links can be directly sent for drainage, and (pornographic) APPs also encourage users to recommend downloads through WeChat QQ, so as to pull new drainage, but later we found that the supervision of the platform is getting stricter and stricter. If you directly send external links to download the app or website address, it will be directly banned by WeChat, so it is increasingly difficult to do drainage on the regular platform."

Zhong Guangjun, director and security expert of WeChat Security Risk Control Center, told the reporter that the external chain includes card links and picture QR codes in the form of presentation. "According to the" WeChat External Link Management Specification ",we divide the standards of violations into 19 categories, including common induced sharing, vulgar spam advertisements, praise collection, fraud and so on. Since January this year, we have dealt with more than one million illegal external chains that have been confirmed by evidence. The overall number of illegal external chains has decreased by 35%, the links of induced sharing classes have decreased by 40%, and the red envelope fraud category has continued to decline by 60%. "

"Our vision is to hope that WeChat friends circle and WeChat chat are places to share life bits and pieces, but some black and gray places just make a fuss about using external links to induce users to share and spread. These illegal external links often contain some malicious content such as junk marketing, vulgarity and fraud, which seriously undermines the normal experience of our normal users and even affects the healthy ecology of the platform. In addition, such a large number of illegal external chains have extended a series of black and gray industries. For example, in order to avoid the security strategy and crackdown needs of WeChat, illegal external chains need to reserve a large number of URLs and a large number of network domain names, which not only seriously harms the WeChat platform, but even affects the development order and norms of the entire Internet. " Zhong Guangjun said.

Shell Finance reporter noted that in order to crack down on illegal website drainage, Weibo has also upgraded its technology. A few days ago, Weibo announced that there were many illegal contents in Weibo’s comments recently that drained illegal websites outside the station and traded pornographic videos. The station centralized and quickly dealt with this kind of Internet illegal activities, and at the same time triggered a fierce confrontation between illegal organizations and Weibo’s security measures. In order to effectively curb the harassment of Internet piracy on platforms and users, Weibo will further upgrade its technology identification system. At the same time, Weibo has launched a special rectification campaign for malicious marketing accounts for two months. Only from June 12th to 18th, Weibo disposed of more than 80 marketing tubas and 210,000 pornographic and vulgar trumpet.

"It can be seen that malicious traffic actually contains a lot of problems. I feel that it is not enough to rely solely on the work of an Internet company or network platform or rely on the crackdown of the competent authorities. Building a clear network environment requires not only our large network system, but also the participation of Internet platforms, ordinary users, and multiple regulatory authorities and competent authorities in social co-governance." Zhong Guangjun said.
