• What is the cause and solution for SAP error message DIWP1155 - Deassignment of notification &1 not possible due to locked order ?

  The SAP error message DIWP1155 indicates that there is an attempt to deassign a notification from an order, but this action cannot be completed because the order is currently locked. This typically occurs in scenarios where the order is being processed or modified by another user or transaction, preventing any changes to its assignments.
  Cause:
  
  Order Locking: The order associated with the notification is locked by another user or transaction. This can happen if someone is currently editing the order or if a background job is processing it.
  Transaction in Progress: If a transaction that involves the order is still in progress, the system will prevent any changes to ensure data integrity.

  Solution:
  
  Check Order Status: Verify if the order is currently being edited or processed. You can check the order status in the SAP system to see if it is locked.
  Wait for Release: If the order is locked by another user, you may need to wait until that user completes their transaction and releases the lock.
  Identify Locking User: Use transaction codes like SM12 (to view locks) to identify which user or process is holding the lock on the order. If necessary, communicate with that user to resolve the issue.
  Check Background Jobs: If a background job is locking the order, you may need to wait for the job to complete or check if it can be canceled if it is not needed.
  User Permissions: Ensure that you have the necessary permissions to deassign notifications from the order. If not, contact your SAP administrator to review your access rights.
