• What is the cause and solution for SAP error message QA064 - Error: Duplicated inspection lot in memory table (lot no: &1) ?

  The SAP error message QA064, which states "Duplicated inspection lot in memory table (lot no: &1)," typically occurs in the Quality Management (QM) module when there is an attempt to process an inspection lot that is already present in the memory table. This can happen during various operations, such as when trying to create or process inspection lots.
  Cause:
  
  Duplicate Lot Entry: The most common cause of this error is that the inspection lot number specified is already loaded in the memory table, which can happen if the system is trying to process the same lot multiple times.

  Clear Memory Table: If you suspect that the memory table has stale data, you can try to clear it. This can often be done by logging out and logging back into the system or by using transaction codes like /n to refresh the session.
  Close Other Sessions: If you have multiple sessions open, close the other sessions that might be accessing the same inspection lot.
  Check for Background Jobs: Ensure that there are no background jobs or processes that might be locking the inspection lot.
  System Restart: In some cases, a system restart may be necessary to clear any memory issues.
