  Data Synchronization: If there are discrepancies between the ERP and EWM systems, ensure that data synchronization processes are functioning correctly.
  Check for Locks: If the shipment or TU is locked, you may need to wait for the lock to be released or contact your system administrator to resolve the locking issue.
