  The SAP error message TG644 indicates that a table exists in the database and is currently being deleted. This error typically arises during operations that involve database table management, such as when trying to create or modify a table that is in the process of being deleted.
  Cause:
  
  Concurrent Operations: The most common cause of this error is that there are concurrent operations trying to access or modify the same database table. For example, one process may be attempting to delete a table while another is trying to create or modify it.
  Database Locking: The table may be locked due to ongoing transactions or processes that are still using it, preventing the deletion from being completed.
  Inconsistent State: The system may be in an inconsistent state due to a previous operation that did not complete successfully, leaving the table in a state where it cannot be accessed properly.
  
  Solution:
  
  Check for Active Processes: Use transaction codes like SM66 (Global Work Process Overview) or SM50 (Process Overview) to check for any active processes that might be using the table. If you find any, you may need to wait for them to complete or terminate them if they are stuck.
  Database Locks: Use transaction code SM12 to check for any locks on the table. If there are locks, you may need to release them if they are no longer needed.
  Retry the Operation: After ensuring that no other processes are using the table and that there are no locks, retry the operation that caused the error.
  Check for Incomplete Transactions: If the issue persists, check for any incomplete transactions that may have left the database in an inconsistent state. You may need to perform a database consistency check or consult your database administrator.
