In all the basic data of MES system, material information, including material code, name, unit and cost, is very important, and the maintenance workload is very heavy. This part of the data should be generated and maintained in MES system, but enterprises that have implemented ERP will think that the data has been stored in ERP system and need not be re-entered and maintained. It is undoubtedly a convenient and feasible method to import material data directly from ERP system to MES system. However, MES is very meticulous in the management of production materials, which is different from the requirements of inventory and BOM-MRP module. Users will find that many production intermediates needed by MES system have never appeared in ERP system before, so it is necessary to maintain materials in MES system. Some of these materials, such as office supplies, are not needed by MES system. This requires MES system to screen the materials in ERP, and whether the function of new materials is ERP.

At present, Shanghai Yao Ying is the platinum agent of Kingdee Software in Shanghai, mainly engaged in Kingdee's full range of management software and supporting products.
The solution of MES system is to import all ERP materials into the standard bill of materials of MES system. Users can also directly add the required materials to the list, and then import the required materials into another final production bill of materials by selecting these materials. In addition to the initial data maintenance, the daily addition, modification and deletion of materials in ERP system also need to be reflected in the production materials of MES.
2) Purchase and arrival information
In the process of scheduling calculation, MES system needs to extract the expected inventory of materials to ensure the supply of raw materials and meet the production demand. It must be pointed out that there is a fundamental difference between this expected inventory quantity and the inventory quantity provided by the enterprise resource planning inventory module. The objective of MES system is to make a "future" plan, so it needs the estimated quantity of future inventory, while the ERP inventory module provides the "previous" and "current" material quantities. In order to obtain the future inventory quantity, MES system needs to obtain the expected quantity and time of raw materials. This information must be manually input into MES system, but if the user has implemented the ERP procurement module, he can get the data manager ERP from the purchase order information.
In this respect, MES has the function of reading the information related to ERP purchase orders and importing the future inventory of MES system. This requires ERP software to open the data tables related to purchase orders in the database.
3) Sales order information
When does MES need to be scheduled first? Produce what? How much did it produce? "This kind of information. This information is usually stored in the sales order in ERP system, or in modules such as master production planning. In addition to manually re-entering information in MES system, you can also obtain information directly from ERP system and deliver it directly to production scheduling after processing.
