• What is the cause and solution for SAP error message L9044 - HU posting change btwn 2 whse nos. must be done in 2 steps by SAP S/4HANA ?

  The SAP error message L9044 indicates that a handling unit (HU) posting change between two warehouse numbers must be performed in two steps. This is a common scenario in SAP S/4HANA when dealing with handling units and warehouse management.
  Cause:
  The error occurs because the system requires a two-step process for transferring handling units between different warehouse numbers. This is typically due to the need for a more controlled and auditable process when moving inventory between different locations. The two-step process ensures that the handling unit is first removed from the source warehouse and then added to the target warehouse, allowing for better tracking and management of inventory.
  Solution:
  To resolve this error, you need to perform the HU posting change in two distinct steps:
  
  
  Step 1: Remove the Handling Unit from the Source Warehouse
  
  Use the appropriate transaction code (e.g., LT0S for transfer posting) to remove the handling unit from the source warehouse. This step will effectively "deallocate" the handling unit from the original location.
  
  
  
  Step 2: Add the Handling Unit to the Target Warehouse
  
  After successfully removing the handling unit from the source warehouse, use the same or another relevant transaction code to add the handling unit to the target warehouse. This step will allocate the handling unit to the new location.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as LT0S (Transfer Posting), HU02 (Change Handling Unit), or LT10 (Transfer Order) that may be used in the process.
  Warehouse Management Configuration: Ensure that your warehouse management settings are correctly configured to handle handling units and that the necessary warehouse processes are in place.
  Documentation: Refer to SAP documentation or help files for detailed instructions on handling unit management and warehouse processes.
  User Authorizations: Ensure that you have the necessary authorizations to perform these actions in the system.
  
  By following the two-step process, you should be able to successfully complete the handling unit posting change between the two warehouse numbers without encountering the L9044 error.
