• What is the cause and solution for SAP error message LT157 - Difference to source bin only if source sub-item was activated ?

  The SAP error message LT157, which states "Difference to source bin only if source sub-item was activated," typically occurs in the context of warehouse management and inventory handling. This error is related to the handling of stock differences during transfer postings or stock movements in the warehouse.
  Cause:
  The error arises when there is an attempt to process a stock transfer or movement that involves a source bin where the sub-item functionality is not activated. In SAP Warehouse Management (WM), sub-items allow for more granular control of stock within a bin. If the source bin is configured to use sub-items, but the sub-item functionality is not activated for the specific stock item or movement, the system will generate this error.
  Solution:
  To resolve the LT157 error, you can take the following steps:
  
  
  Check Sub-item Activation:
  
  Verify if the source bin is configured to use sub-items. You can do this by checking the bin configuration in the warehouse management settings.
  If sub-items are required for your process, ensure that the relevant stock items are also configured to support sub-items.
  
  
  
  Activate Sub-items:
  
  If sub-items are not activated for the stock item or the source bin, you may need to activate them. This can typically be done in the material master or bin master data settings.
  
  
  
  Adjust Transfer Posting:
  
  If sub-items are not necessary for your process, consider adjusting the transfer posting or stock movement to avoid using sub-items. This may involve changing the configuration of the stock movement or the way the stock is being handled.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help resources related to warehouse management and sub-item handling for more detailed guidance on configuration and troubleshooting.
  
  
  
  Contact SAP Support:
  
  If the issue persists after checking the configurations, consider reaching out to SAP support for further assistance. They can provide insights specific to your system configuration and help troubleshoot the issue.
