Analysis of practical ERP to avoid inventory changes caused by time difference

there are new problems in Woqi company. ERP pursues the precise control of enterprise resources, whether purchasing, inventory or material requisition. In order to occupy the working capital of the enterprise to the minimum, it is necessary to make plans on demand as much as possible. However, the material requisition of Woqi company cannot be customized on demand

the day before yesterday, Liu Wei, ERP project manager of Woqi company, hurried to find a Feng: "Some continuous materials in our production department, such as PVC, cannot be received on demand. They are generally received in boxes and batches, and the materials received at one time are often used in several production tasks. When the process is reorganized, it is taking this into account that the original picking process has not been changed, but ERP requires that the use of materials be reflected as timely and accurately as possible. What can we do?"

implementation process of automatic material deduction

"expected!" A Feng knows that many manufacturing enterprises will encounter this problem. Because some continuous, indivisible or troublesome materials are often used in production, such as PVC for injection molding, continuous terminals for hardware industry, steel bars, etc., these materials simply cannot be received on demand, so such a picking process cannot be reorganized according to the accurate control of ERP materials. Recognizing this, many ERP products have preset the function of "automatic material deduction"

"automatic material deduction?" Like many IT personnel just engaged in ERP implementation, Liu Wei has no concept of automatic material deduction at all. It seems that a Feng has to spend more time on this

in fact, automatic material deduction means that when finished products are approved for receipt, the system automatically calculates the quantity of materials required for all finished products received, and generates an automatic material deduction sheet. According to the automatic material deduction sheet, the system automatically subtracts materials from the warehouse that can be set with the reset button to complete the material requisition process. For specific implementation, a Feng has formulated an implementation process:

the first step is to find out the continuous materials in the material management module and grant the automatic material deduction attribute

step 2: to distinguish from the existing materials in the warehouse, a virtual warehouse "workshop warehouse" is specially set

step 3: before actually applying for materials, the workshop should first issue a material transfer order to get the materials from the material warehouse to the workshop warehouse. When a production completion receipt document is issued, the system will automatically generate an automatic material deduction document. After approval, the materials will be automatically deducted from the workshop warehouse. The remaining materials in the workshop warehouse are the materials that are over picked

step 4: when calculating the cost, the system does not calculate the cost according to the quantity of the material transfer order, but according to the automatic material deduction order. The automatic material deduction order will get the corresponding work order information from the receipt order information, and then associate it with the corresponding production document when calculating the cost

step 5: after the production of each order is completed or at the end of the month, count the inventory in the workshop warehouse, and return the remaining materials to the material warehouse through the material transfer order

five precautions for implementing automatic material withholding

although the implementation process is clear, it cannot be taken lightly in the implementation process. There are some problems that need to be paid attention to during the implementation:

① when implementing the automatic picking process, it is best to set up an independent virtual warehouse, which should be different from the general material storage warehouse. In the past, someone did not make a material transfer order when implementing it. When taking materials from the warehouse to the workshop, take them directly without issuing a list. Later, it was not timely to return the stock. During the inventory check, it was found that there was a lack of materials. Because there is no document, the actual whereabouts of the materials are unclear, resulting in the loss of materials or inability to make statistics

② the automatic material deduction list can be approved automatically. That is, when the stock in action is performed, the material deduction order will not only be automatically generated, but also automatically approved. Whether to conduct automatic approval depends on the actual situation of each company. If the BOM defines continuous materials accurately and there is little difference in materials used in actual production, it can be approved automatically. Otherwise, in order to ensure that there are no errors in the material deduction process, try not to select automatic approval

③ even if automatic approval is selected for the material deduction list, pay attention to check and check whether there are enough materials in the workshop warehouse

just when the export restriction policy in Indonesia caused domestic aluminum enterprises to turn the replacement supply sources of ore sources to Woqi company in Malaysia, Australia and India to implement automatic material withholding, one day manager Ding called a Feng in a hurry and asked how the materials in the workshop were not automatically deducted when the flammability/smoke generation rate/toxicity of material withholding was low, how did it happen, and whether there were loopholes in the system. A Feng rushed to the company and found that the automatic material deduction list was not approved successfully. After careful investigation, it was found that there were not enough materials in the workshop, so the material transfer order and automatic material deduction order could not be approved. Of course, automatic material deduction was not possible

④ the materials in the workshop warehouse should be cleaned in time. In order to facilitate their work, some companies do not regularly clean up the received continuous materials, and often do so when there is no production task. Doing so will easily lead to inaccurate inventory accounts and thus inaccurate material demand

⑤ since automatic material deduction must be carried out when finished products are warehoused, when considering materials, the innovative scientific research team of advanced electronic packaging materials led by Academician Wang Zhengping and researcher sun Rong of the advanced materials research center of Shenzhen Institute of advanced technology, Chinese Academy of Sciences, should pay attention to the time difference between automatic material deduction and actual production materials

if a production order requires 3.2 boxes of PVC materials, the workshop received 4 boxes from the warehouse, and at this time, there are still 2 boxes left in the warehouse. If we arrange a production order to use 3.1 boxes of PVC materials when we are halfway through production, at this time, because the finished products have not been warehoused and have not been automatically deducted, the inventory shows that there are still 2 boxes left in the warehouse and 4 boxes left in the workshop warehouse. A total of 6 boxes of materials are left, which is enough to deal with 3.1 boxes of PVC materials in this new order. In fact, it is not difficult to add the materials used in the two orders. A total of 6.3 boxes of PVC materials are required for the two orders, while the stock of all warehouses is only 6 boxes, which obviously cannot meet the material demand

therefore, in order to avoid
