Tip of the Day: Diagnosis in SM12

I will be adding a new topic under the heading Tip of the Day. This is one is given to me by Yahya Dossary, a Senior Operating System Specialist, a colleague and a good friend at my workplace. This is printed with his permission with some added notes from me.


T/C is used for displaying and deleting locks in SAP systems. Report used to generate SM12 is RSENQRR2.

To check the status of a SAP system locking management mechanism you can use transaction code sm12 as shown below. The option Diagnosis in Update simulates a looking operation.

I hope this will be helpful to somebody.
