  The SAP error message LF151 "Duplicate lines in transfer order &1" typically occurs when there are duplicate entries in a transfer order (TO) that you are trying to process. This can happen during various operations, such as creating, changing, or processing transfer orders in the Warehouse Management (WM) module.
  Cause:
  
  Duplicate Items: The transfer order may contain multiple entries for the same material and storage location, which is not allowed.
  Data Entry Errors: During the creation of the transfer order, the same item may have been entered more than once.
  System Configuration Issues: There may be issues with the configuration of the warehouse management system that allow duplicates to be created.
  
  Solution:

  Deleting the duplicate line items from the transfer order.

  Check for System Issues: If duplicates are being created frequently, it may be worth investigating the processes or transactions that lead to this issue. Ensure that users are trained properly and that there are no system bugs or configuration issues.
