• What is the cause and solution for SAP error message TB102 - Table & locked by you ?

  The SAP error message TB102, which states "Table & locked by you," typically occurs when a user tries to access or modify a table that is currently locked by their own session. This can happen in various scenarios, such as when a user is editing a table in transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser) and does not properly release the lock.
  Cause:
  
  User Lock: The user has opened a table in a transaction that locks it for editing or viewing.
  Unfinished Transactions: The user may have an unfinished transaction that has not been properly closed, leaving the table in a locked state.
  Session Issues: Sometimes, if a user has multiple sessions open, they may inadvertently lock a table in one session while trying to access it in another.
  
  Solution:
  
  
  Release the Lock:
  
  If you are aware of the session where the table is locked, you can simply close that session or transaction to release the lock.
  If you are unsure, you can use transaction code SM12 (Display and Delete Locks) to view and delete your own locks. Here’s how:
  
  Go to transaction SM12.
  Enter your user ID and execute the search.
  Identify the lock entries related to the table in question.
  Select the relevant entries and delete them to release the lock.
  
  
  
  
  
  Check for Active Sessions:
  
  Use transaction AL08 to check for active user sessions. This can help you identify if you have multiple sessions open that might be causing the lock.
  
  
  
  Wait and Retry:
  
  If the lock is not from your own session, you may need to wait for the other user to complete their transaction and release the lock.
  
  
  
  Contact Administrator:
  
  If you are unable to resolve the issue yourself, consider reaching out to your SAP system administrator for assistance. They can help identify the cause of the lock and take necessary actions.

  Best Practices: To avoid encountering this error frequently, ensure that you properly close transactions and sessions when you are done working with tables. Regularly check for and clear any unnecessary locks in your user sessions.
  
  
  By following these steps, you should be able to resolve the TB102 error and continue your work in SAP.
