• What is the cause and solution for SAP error message /ISDFPS/FDPDAMPO081 - Handling unit &1 already assigned to requisition &2 ?

  The SAP error message /ISDFPS/FDPDAMPO081 Handling unit &1 already assigned to requisition &2 indicates that a specific handling unit (HU) is already linked to a requisition, and you are attempting to assign it to another requisition. This situation typically arises in the context of logistics and inventory management within SAP, particularly when dealing with handling units in the context of delivery or shipment processes.
  Cause:
  
  Duplicate Assignment: The handling unit (HU) you are trying to assign is already associated with another requisition. In SAP, each handling unit can only be assigned to one requisition at a time to maintain data integrity and avoid confusion in inventory management.
  System Configuration: There may be specific configurations or settings in your SAP system that enforce strict rules regarding the assignment of handling units to requisitions.
  
  Solution:
  
  Check Current Assignment: Verify which requisition the handling unit is currently assigned to. You can do this by using transaction codes like HU02 (Display Handling Unit) to view the details of the handling unit and see its current assignments.
  Reassign Handling Unit: If you need to reassign the handling unit to a different requisition, you will first need to unassign it from the current requisition. This can typically be done through the appropriate transaction for managing handling units, such as HU02 or VL02N (Change Outbound Delivery).
  Create a New Handling Unit: If the handling unit must remain assigned to the original requisition, consider creating a new handling unit for the new requisition instead of trying to reassign the existing one.
  Consult Documentation: Review SAP documentation or your organization's internal guidelines for handling units and requisitions to ensure compliance with best practices.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  HU02: Display Handling Unit
  HU01: Create Handling Unit
  VL02N: Change Outbound Delivery
  VL03N: Display Outbound Delivery
  
  
  SAP Notes: Check SAP Notes for any known issues or updates related to handling units and requisition assignments.
  User Authorization: Ensure that you have the necessary authorizations to make changes to handling units and requisitions in the system.
  Training and Support: If you are unsure about the process, consider reaching out to your SAP support team or attending training sessions on handling units and logistics processes in SAP.
  
  By following these steps, you should be able to resolve the error and manage handling units effectively within your SAP environment.
