• What is the cause and solution for SAP error message /ISDFPS/MSG_GAF_PE128 - Item &1: Handling unit &2 is already contained in the issue list ?

  The SAP error message /ISDFPS/MSG_GAF_PE128 indicates that a handling unit (HU) is already included in the issue list for a specific item. This typically occurs in the context of logistics and inventory management, particularly when dealing with handling units in the SAP Extended Warehouse Management (EWM) or similar modules.
  Cause:
  The error is triggered when you attempt to add a handling unit to an issue list (for example, during a goods issue or transfer process) that has already been included in that list. This can happen due to:
  
  Duplicate Entry: The handling unit has already been processed or marked for the same operation.
  System Logic: The system prevents the same handling unit from being processed multiple times to avoid inconsistencies in inventory management.
  User Error: The user may have inadvertently tried to add the same handling unit again.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Issue List: Review the issue list to confirm that the handling unit is indeed already included. You can do this by navigating to the relevant transaction or report that displays the issue list.
  
  
  Remove Duplicate Entry: If the handling unit is mistakenly included, you may need to remove it from the issue list before attempting to add it again.
  
  
  Verify Handling Unit Status: Ensure that the handling unit is in a status that allows it to be processed. If it is locked or in a different state, you may need to change its status.
  
  
  Consult Documentation: Refer to SAP documentation or help files related to handling units and issue lists for specific instructions on how to manage these entries.
  
  
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide further assistance.
