• What is the cause and solution for SAP error message CNV_PE662 - Warehouse management is not active ?

  The SAP error message CNV_PE662: Warehouse management is not active typically occurs when you are trying to perform operations related to warehouse management in an SAP system where the Warehouse Management (WM) module is not activated. This can happen during data migration, system configuration, or when trying to execute certain transactions that require WM functionality.
  Cause:
  
  Warehouse Management Not Activated: The most common cause is that the Warehouse Management module is not activated in the system. This can happen if the system is configured to use Inventory Management (IM) without WM.

  Use Correct Transactions:
  
  If your business process does not require WM, ensure that you are using the correct transactions that are compatible with Inventory Management only.
