• What is the cause and solution for SAP error message /SCWM/HU_WM138 - HU &1 is already posted GR and cannot be updated with new planned stock ?

  The SAP error message /SCWM/HU_WM138 HU &1 is already posted GR and cannot be updated with new planned stock typically occurs in the context of handling units (HUs) in the Extended Warehouse Management (EWM) module. This error indicates that the handling unit (HU) you are trying to update has already been posted for Goods Receipt (GR), and therefore, it cannot be modified to reflect new planned stock.
  Cause:
  
  Goods Receipt Already Posted: The handling unit has already been processed for a goods receipt, meaning that the stock has been officially recorded in the system.
  Attempting to Update: You are trying to update the handling unit with new planned stock, which is not allowed since the HU is already in a finalized state regarding its stock status.
  
  Solution:
  
  Check HU Status: Verify the status of the handling unit in the system. If it has already been posted for GR, you will need to consider the implications of that status before making any changes.
  Create a New Handling Unit: If you need to add new stock, consider creating a new handling unit instead of trying to modify the existing one.
  Reverse the GR (if applicable): If it is necessary to change the stock associated with the handling unit, you may need to reverse the goods receipt. This should be done with caution, as it can affect inventory and accounting records.
  Consult Documentation: Review SAP documentation or consult with your SAP support team for specific procedures related to handling units and goods receipts in your version of SAP EWM.
