[0011] Reduce errors: Reduce errors caused by subjective factors, such as inventory record errors, etc. The system provides real-time business data verification, reminding operators to perform accurate operations, thereby reducing the error rate.

[0012] Accurately and efficiently manage the warehouse in an integrated manner: from the traditional "results-oriented" to "process-oriented"; from "data entry" to "data collection / integration", while being compatible with the original "data entry" mode; from "manual search for goods" to "guided positioning and picking up goods". The essence of material information management is the logic that the process is precisely controllable and the result is naturally correct. Specific implementation method:

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] Embodiment 1:

[0016] Purchasing warehousing: SAP initiates a purchase order and pushes the purchase warehousing task to WMS. Operations notify warehouse personnel of vehicle arrival and remind the task in WMS. When the vehicle arrives at the designated location, the task information is automatically generated by the coil label (coil width, outer diameter, weight, etc.) transmitting a wireless signal to enter the warehouse. If the goods match, the document is automatically completed and pushed to SAP to complete the purchase order. If the goods do not match the task order, the operation is notified to request instructions for operation. Operations can assist in the forced completion of the task. The completed task results are fed back to SAP (warehousing / accounting results).

[0017] After the steel coil is scored and put into storage, the staff of the scoring production line will update the coil label information. The scoring information will be pushed to WMS when MES reports production, and the information will be synchronized to SAP to increase inventory.

[0018] The strips are rolled into the warehouse, and after longitudinal cutting, the strips are rolled and labeled. The labels can transmit wireless signals, and the base station receives the wireless signals to locate the position of the rolls in real time and obtain the information of the rolls.

[0019] The slitting return material is put into storage. The slitting production line personnel return the remaining material to the raw material warehouse, perform the return operation in MES, enter the return information, MES transmits the return task to WMS, the warehouse screen displays the return information, the trolley delivers the material to the return port, and the returned coil material updates the coil label and is put into storage.

[0020] Transfer to warehouse, SAP maintains the transfer to warehouse, after the transfer out, automatically pushes the transfer outbound order to WMS, WMS receives the transfer to warehouse task, waits for the operation to feedback to the vehicle, WMS reminds the pending task, the warehouse staff checks the goods and updates the label to enter the warehouse, if the goods do not match the task order, the operation is notified to request the instruction operation, and the operation can assist in the forced completion of the task. The completed task results are fed back to SAP (warehouse / accounting results).

[0021] For other incoming warehousing, there are other types of outgoing warehousing, such as the incoming warehousing of inventory surplus. The remarks are clearly written, and the task is initiated from SAP. The WMS warehouse staff receives the task, updates the coil label information, and feeds the results back to SAP to complete other incoming warehousing.

[0022] After the steel coil is scored and put into storage, the staff of the scoring production line will update the coil label information. The scoring information will be pushed to WMS when MES reports production, and the information will be synchronized to SAP to increase inventory.

[0023] When transferring warehouses and adjusting inventory, the warehouse administrator only needs to move the material to the storage location / area. There is no need to manually scan the materials. The warehouse can be directly transferred and the data can be updated to the WMS system.
