• What is the cause and solution for SAP error message /SCMB/VMI_APO029 - Function module /SAPAPO/MSDP_TSER_EXT_PUT: Sales data locked ?

  The SAP error message /SCMB/VMI_APO029 indicates that there is an issue with the function module /SAPAPO/MSDP_TSER_EXT_PUT, specifically that sales data is locked. This typically occurs in the context of the SAP Advanced Planning and Optimization (APO) module, particularly in the Vendor Managed Inventory (VMI) scenario.
  Cause:
  
  
  Data Locking: The error usually arises when the sales data that the function module is trying to access is currently locked by another process. This can happen if:
  
  Another transaction is currently processing the same data.
  A previous transaction did not release the lock properly.
  There is a long-running process that is holding the lock.
  
  
  
  Concurrency Issues: If multiple users or processes are trying to access or modify the same sales data simultaneously, it can lead to locking issues.
  
  
  System Configuration: Sometimes, the configuration settings in the APO system may lead to unexpected locking behavior.
  
  
  Solution:
  
  
  Identify the Lock: Use transaction code SM12 to check for existing locks. You can filter by user or object to find out which process is holding the lock on the sales data.
  
  
  Release the Lock: If you identify a lock that is no longer needed (e.g., from a user session that has ended), you can manually delete the lock entry in SM12. However, be cautious when doing this, as it may affect other users or processes.
  
  
  Check for Long-Running Processes: Use transaction code SM66 to monitor active processes in the system. If you find a long-running process that is holding the lock, you may need to investigate further or terminate it if appropriate.
  
  
  Review Custom Code: If you have custom code that interacts with the sales data, review it to ensure that it properly handles locks and releases them when done.
  
  
  System Configuration: Review the configuration settings related to locking in your APO system. Ensure that they are set up correctly to minimize locking issues.
  
  
  Retry the Operation: After resolving the locking issue, retry the operation that triggered the error.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional troubleshooting steps.
  Documentation: Review the SAP APO documentation for best practices regarding data locking and concurrency management.
  Support: If the issue persists, consider reaching out to SAP support for further assistance, especially if it is impacting business operations.
  
  By following these steps, you should be able to diagnose and resolve the locking issue related to the /SCMB/VMI_APO029 error message.
