  The SAP error message /STTPEC/MSG007 Report is locked by user &1. Only a single instance can be executed. indicates that a specific report or transaction is currently being executed by another user, and as a result, you cannot run the same report simultaneously. This is a common locking mechanism in SAP to prevent data inconsistencies and ensure that reports are processed in a controlled manner.
  Cause:
  
  Concurrent Execution: The report is designed to allow only one instance to run at a time. If another user is already executing the report, it will lock the report for other users.
  Long-Running Processes: If the report takes a long time to execute, it may remain locked for an extended period, preventing others from running it.
  User Session Issues: Sometimes, a user may have an active session that is not properly terminated, causing the report to remain locked.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait until the user who is currently running the report completes their task. You can check with the user if they are still running the report.
  Check Active Sessions: Use transaction code SM50 (or SM66 for global monitoring) to check for active processes. Look for the report in the list and see which user is executing it.
  Terminate the Process: If you have the necessary authorizations and determine that the report is stuck or running longer than expected, you can terminate the process. In SM50, select the process and choose the option to "End Process."
  Contact the User: If you know who the user is, you can contact them to see if they can finish or cancel their execution of the report.
  Review Report Design: If this is a frequent issue, consider reviewing the report design to see if it can be modified to allow multiple instances or to improve performance.
