• What is the cause and solution for SAP error message /SCWM/RF_EN179 - Post difference at sub-HU level ?

  The SAP error message /SCWM/RF_EN179 indicates that there is a post difference at the sub-handling unit (sub-HU) level in the SAP Extended Warehouse Management (EWM) system. This error typically arises when there is a discrepancy between the expected and actual quantities of handling units during inventory management processes, such as goods receipt, goods issue, or stock transfers.
  Cause:
  
  
  Inventory Discrepancies: The most common cause is a mismatch between the physical inventory and the system inventory. This can occur due to:
  
  Manual adjustments made to inventory without corresponding updates in the system.
  Errors during the handling unit creation or processing.
  Incomplete or incorrect data entry during goods movements.
  
  
  
  Sub-HU Management: If sub-handling units are being used, discrepancies can arise if the quantities in the sub-HUs do not match the expected quantities in the parent handling unit.
  
  
  System Configuration Issues: Incorrect configuration of handling units or inventory management settings can lead to discrepancies.
  
  
  Solution:
  
  
  Check Inventory Levels: Verify the physical inventory against the system records. Conduct a physical count if necessary to identify discrepancies.
  
  
  Adjust Inventory: If discrepancies are found, make the necessary adjustments in the system to align with the physical inventory. This may involve:
  
  Performing a stock adjustment transaction.
  Updating the handling unit information to reflect the correct quantities.
  
  
  
  Review Handling Unit Data: Check the handling unit and sub-HU data for any inconsistencies. Ensure that all handling units are properly created and that their quantities are accurately reflected in the system.
  
  
  Reprocess the Transaction: If the error occurred during a specific transaction, try to reprocess that transaction after correcting any discrepancies.
  
  
  Consult Documentation: Review SAP documentation or notes related to handling units and inventory management for any specific guidance or known issues.
  
  
  System Configuration Review: If the issue persists, review the configuration settings for handling units in the EWM system to ensure they are set up correctly.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM, such as /SCWM/PRDI for physical inventory or /SCWM/HU for handling unit management.
  User Roles and Authorizations: Ensure that users have the necessary roles and authorizations to perform inventory adjustments and handling unit management.
  
  If the issue continues after following these steps, it may be beneficial to engage with SAP support or consult with a technical expert familiar with EWM for further assistance.
