• What is the cause and solution for SAP error message MM_PUR_COMMON_API004 - Only PATCH operations supported in change set ?

  The SAP error message MM_PUR_COMMON_API004: Only PATCH operations supported in change set typically occurs when there is an attempt to perform an operation that is not allowed in the context of a change set in the SAP system, particularly when using the OData services for managing purchase orders or related entities.
  
  Cause:
  
  
  Incorrect HTTP Method: The error indicates that the operation being attempted is not a PATCH operation. In OData, a PATCH request is used to update an existing resource, while POST is used to create a new resource, and DELETE is used to remove a resource. If you are trying to perform an operation that is not a PATCH (like POST or PUT) within a change set, this error will occur.
  
  
  Change Set Misconfiguration: If you are using a change set to group multiple operations together, and one of those operations is not a PATCH, the system will throw this error.
