Introduction:
An essential aspect of supply chain management is maintaining the accuracy of inventory records. SAP Extended Warehouse management is the most powerful module in the SAP ERP portfolio to manage physical inventory. This blog covers how to do physical inventory in SAP EWM, its importance, and how to manage the warehouse effectively.
Physical inventory involves counting the goods in a warehouse and comparing stock to records to verify stock level and condition. This process helps you identify discrepancies between the actual physical stock in the warehouse and the system records to correct them and show any data entry, theft, or damage issues.
Process flow:
Create Physical Inventory:
Physical inventory document creation is vital in inventory management since it is the base for a successful inventory count. PI can be created with reference to either storage bin, material, or activity area. We must use the transaction code /N/SCWM/PI_CREATE to create a physical inventory document.
Count:
The count refers to the activity performed to check the physical stock quantities available in the warehouse against the recorded inventory data in the system.
Post:
The post refers to validating and updating inventory movements on a warehouse management system.
Recount and Post:
Recount is an activity directly related to taking another look at certain items or areas of inventory that had a ‘Discrepancy’ reported against them during the initial physical inventory count.
Difference Analyzer:
Difference Analyzer is a tool to analyze the difference between physical inventory documents of stock levels in a warehouse and actual inventory levels in the warehouse.
