  The SAP error message /PF1/MSG_PO_E756 Object was locked. Will retry in 2 seconds. indicates that a particular object (such as a purchase order, material, or other business object) is currently locked by another user or process. This locking mechanism is a standard feature in SAP to prevent data inconsistencies that can occur when multiple users attempt to modify the same object simultaneously.
  Cause:
  
  Concurrent Access: Another user or process is currently accessing or modifying the object, leading to a lock.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on the object longer than expected.
  System Performance Issues: If the system is slow, it may take longer for the lock to be released.
  Deadlocks: In some cases, a deadlock situation may occur where two processes are waiting for each other to release locks.
  
  Solution:
  
  Wait and Retry: The message indicates that the system will automatically retry after 2 seconds. Often, simply waiting for a moment will resolve the issue if the lock is temporary.
  Identify the Lock: If the issue persists, you can use transaction code SM12 to check for active locks. You can see which user or process is holding the lock and take appropriate action.
  Release the Lock: If you have the necessary authorizations, you can manually release the lock from SM12. However, be cautious when doing this, as it may disrupt the work of other users.
  Check for Long-running Transactions: Use transaction SM66 (Global Work Process Overview) or SM50 (Work Process Overview) to identify any long-running processes that may be holding locks.
  Consult with the User: If you identify the user or process holding the lock, you may want to communicate with them to understand why the lock is in place and if it can be released.
  System Performance Tuning: If locks are a frequent issue, consider reviewing system performance and tuning it to reduce the time locks are held.
