Hi Pannkaj
Please check the result of below steps if OK?
SAP SM12 -> Goto/Extra -> Diagnosis/Diagnosis in Update and
SAP SM12 -> “test” in OK/command window then you will see extra option in menu bar Error handling -> Diagnosis Environment.
Check SM21, enqueue logs in ASCS folder. Was there any connectivity issue with enqueue service?
Regard
