• What is the cause and solution for SAP error message /SCWM/ODATA_API004 - Use separate change sets for WO assignment and unassignment ?

  The SAP error message /SCWM/ODATA_API004 Use separate change sets for WO assignment and unassignment typically occurs in the context of the SAP Extended Warehouse Management (EWM) system when using the OData API for handling work orders (WOs). This error indicates that the system requires separate change sets for assigning and unassigning work orders.
  Cause:
  The error arises because the OData API is designed to handle work order assignments and unassignments in distinct operations. When a request attempts to perform both actions (assignment and unassignment) in a single change set, the system rejects it, leading to this error message.
  Solution:
  To resolve this error, you need to separate the operations into different change sets. Here’s how you can do that:
  
  
  Separate Change Sets: 
  
  Create one change set for assigning work orders.
  Create another change set for unassigning work orders.
  
  This means that if you are trying to assign a work order and unassign another in the same API call, you should split them into two separate API calls.
  
  
  API Call Structure:
  
  Ensure that your API calls are structured correctly. For example, if you are using a batch request, make sure that the requests for assignment and unassignment are in different batch requests.
  
  
  
  Testing:
  
  After making the changes, test the API calls to ensure that they work as expected without triggering the error.
  
  
  
  Related Information:
  
  SAP Documentation: Refer to the official SAP documentation for the OData API related to EWM for detailed guidelines on how to structure your requests.
  SAP Community: Engage with the SAP Community forums for insights and experiences from other users who may have encountered similar issues.
  Error Handling: Implement error handling in your application to catch this specific error and provide meaningful feedback to users or logs for troubleshooting.
  
  By following these steps, you should be able to resolve the error and successfully manage work order assignments and unassignments in SAP EWM using the OData API.
