• What is the cause and solution for SAP error message TN850 - Import phase '&1' (&2, &3) started in background ?

  The SAP error message TN850 typically indicates that there is an issue during the import phase of a transport request. This message is often seen in the context of transport management, where changes are being moved from one SAP system to another (e.g., from a development system to a quality assurance or production system).
  Cause:
  The error message TN850 itself is more of an informational message rather than an error. It indicates that the import phase has started in the background. However, if you are experiencing issues related to this message, it could be due to several reasons:
  
  Long-running import: The import process may take a long time, and you might be checking the status too early.
  Lock issues: There may be locks on database tables or objects that are preventing the import from completing.
  Transport inconsistencies: The transport request may have inconsistencies or dependencies that are not met in the target system.
  Background job issues: The background job responsible for the import may have encountered issues or failed.
  
  Solution:
  To address the issues related to the TN850 message, you can take the following steps:
  
  Check the Import Status: Use transaction code STMS to check the status of the transport request. Look for any errors or warnings in the import logs.
  Review Logs: Check the transport logs for detailed error messages. You can find logs in transaction ST22 (dump analysis) or SM21 (system log).
  Monitor Background Jobs: Use transaction SM37 to monitor background jobs. Look for the job related to the transport import and check its status.
  Check for Locks: Use transaction SM12 to check for any locks that might be preventing the import from completing. If you find locks that are no longer needed, you can delete them (with caution).
  Dependencies: Ensure that all dependencies for the transport request are met. This includes checking for any required objects or configurations that need to be in place before the import.
  Retry the Import: If the import has failed, you may need to retry it after resolving any identified issues.
  
  Related Information:
  
  Transport Management System (TMS): Familiarize yourself with TMS and how it manages transport requests between different SAP systems.
  SAP Notes: Check SAP Notes for any known issues related to transport imports. You can search for specific error codes or messages in the SAP Support Portal.
