• What is the cause and solution for SAP error message CONV155 - &3: &2 even after &1 attempts not successful, remove lock manually ?

  The SAP error message CONV155 typically indicates that there is a problem with a conversion or processing of data in the system, and it often relates to issues with locks on database entries or objects. The message suggests that the system has attempted to perform an operation multiple times (in this case, &1 attempts) but has not been successful, and it advises the user to manually remove the lock.
  Cause:
  
  Database Lock: The most common cause of this error is that a database entry or object is locked by another user or process. This can happen if a transaction is not completed properly or if a user has left a session open.
  Long-running Transactions: If a transaction takes too long to complete, it may hold locks longer than expected, causing other processes to fail.
  Deadlocks: In some cases, deadlocks can occur where two or more processes are waiting for each other to release locks, leading to a situation where neither can proceed.
  System Errors: There may be underlying system errors or issues with the database that are causing the locks to persist.
  
  Solution:
  
  Identify the Lock: Use transaction codes like SM12 (Display and Delete Locks) to identify the locks that are causing the issue. You can see which user or process is holding the lock.
  Remove the Lock: If you have the necessary authorizations, you can manually delete the lock entries from SM12. Be cautious when doing this, as removing locks held by other users can lead to data inconsistencies or loss of unsaved work.
  Check for Long-running Transactions: Use transaction codes like SM66 (Global Work Process Overview) or SM50 (Work Process Overview) to check for long-running transactions that may be holding locks.
  Review System Logs: Check the system logs (transaction code SM21) for any errors or warnings that may provide additional context about the issue.
  Restart the Process: After removing the lock, try to rerun the process that was failing to see if the issue is resolved.
  Consult Basis Team: If the issue persists, it may be necessary to involve your SAP Basis team to investigate further, especially if there are underlying database issues.
