• What is the cause and solution for SAP error message PV629 - Table could not be locked ?

  The SAP error message PV629, which states "Table could not be locked," typically occurs when a process attempts to access a database table that is already locked by another transaction. This can happen in various scenarios, such as during data updates, inserts, or deletes when multiple users or processes are trying to access the same table simultaneously.
  Causes:

  Solutions:
  
  Wait and Retry: If the error is due to temporary locking, waiting for a few moments and then retrying the operation may resolve the issue.
