• What is the cause and solution for SAP error message /SCWM/CONS_CHECK021 - No. of HUs for main bin &1 differs from the sum of HUs of the sub-bins ?

  The SAP error message /SCWM/CONS_CHECK021 indicates a discrepancy between the number of Handling Units (HUs) in a main bin and the sum of the HUs in its sub-bins. This error typically arises in the context of warehouse management within the SAP Extended Warehouse Management (EWM) module.
  Cause:
  
  
  Data Inconsistency: The most common cause is a data inconsistency where the system records for the main bin and sub-bins do not match. This can happen due to:
  
  Manual adjustments or errors in inventory management.
  Incomplete or incorrect postings during goods movements.
  System errors during the creation or deletion of HUs.
  
  
  
  Incorrect Configuration: If the warehouse structure is not configured correctly, it may lead to discrepancies in HU counts.
  
  
  Unprocessed Transactions: There may be pending or unprocessed transactions that have not been reflected in the system, leading to mismatched counts.
  
  
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Check HU Counts: 
  
  Verify the number of HUs in the main bin and compare it with the sum of HUs in the sub-bins. You can do this using transaction codes like /SCWM/PRDI (for displaying handling units) or through the EWM monitor.
  
  
  
  Reconcile Data:
  
  If discrepancies are found, you may need to adjust the HUs in either the main bin or the sub-bins to ensure they match. This can involve:
  
  Moving HUs between bins.
  Creating or deleting HUs as necessary.
  
  
  
  
  
  Review Transactions:
  
  Check for any unprocessed or erroneous transactions that may have caused the inconsistency. Ensure that all goods movements are correctly posted.
  
  
  
  System Logs:
  
  Review system logs for any errors or warnings that may provide additional context for the issue.
  
  
  
  Configuration Check:
