“Users are getting the error ‘The column prefix UPR00100 does not match with a table name or alias name used in the query’ followed by ‘Procedure changerGLIdx did not run properly’ while running GL Changer.”

This error is caused by a conflict with trigger zDT_UPR00100U on table UPR00100 while changing the account index in table UPR00100. Disabling this trigger temporarily while running Changer would resolve this issue. Enable the trigger again after Changer processing is complete.
