• What is the cause and solution for SAP error message /SCWM/GM771 - Simultaneous posting of differences for multiple WT items is not possible ?

  The SAP error message /SCWM/GM771 indicates that there is an attempt to post differences for multiple Warehouse Task (WT) items simultaneously, which is not allowed in the system. This error typically arises in the context of warehouse management processes, particularly when dealing with goods movements and inventory discrepancies.
  Cause:
  The primary cause of this error is that the system does not support simultaneous posting of differences for multiple WT items. This restriction is in place to ensure data integrity and to avoid conflicts that may arise from processing multiple items at the same time.
  Solution:
  To resolve this error, you can follow these steps:
  
  
  Single Item Processing: Instead of trying to post differences for multiple WT items at once, process each WT item individually. This means you should select one WT item, post the difference, and then move on to the next item.
  
  
  Check WT Status: Ensure that the Warehouse Tasks you are trying to process are in a status that allows for posting differences. If a WT is locked or in a status that does not permit changes, you may encounter this error.
  
  
  Review Configuration: If you frequently encounter this error and it disrupts your workflow, consider reviewing the configuration settings in your SAP system. Consult with your SAP WM/SCM consultant to see if there are any settings that can be adjusted to better suit your operational needs.
  
  
  Transaction Codes: Use the appropriate transaction codes for posting differences. For example, you might use transaction codes like LT01 (Create Transfer Order) or LT10 (Confirm Transfer Order) depending on your specific needs.
  
  
  Error Logs: Check the system logs for any additional error messages or warnings that may provide more context about the issue. This can help in diagnosing if there are underlying issues contributing to the error.
  
  
  Related Information:
