• What is the cause and solution for SAP error message QT400 - Inspection lot &1 operation &2 is blocked by another user at present ?

  The SAP error message "QT400 Inspection lot &1 operation &2 is blocked by another user at present" typically occurs when a user attempts to access or modify an inspection lot that is currently being processed or locked by another user. This is a common scenario in environments where multiple users are working with the same data simultaneously.

  Session Issues: Sometimes, a user may have an open session that is not properly closed, causing the lock to persist.
  Background Jobs: If there are background jobs or batch processes that are accessing the same inspection lot, they may also cause locks.
