Résumé :
In an SAP environment, users may encounter extensive process delays in transaction SM66 due to locks on QIWKTB by processes accessing TRFCQIN, leading to unprocessed inbound queues. This locking occurs as dependencies are verified during the queue scheduler's exit phase. The resolution involves applying attached corrections to address these scheduling and locking challenges.
