Hi Ravi,
Specifically for SAP PI I use the following jobs:
No. Program /Command
1 RSXMB_CANCEL_MESSAGES
2 SXMS_REFRESH_ADAPTER_STATUS
3 RSXMB_DELETE_MESSAGES
4 RSXMB_DELETE_HISTORY
5 RSBTCDEL2
6 SBAL_DELETE
7 SXMS_PF_REORG
8 RSWF_XI_INSTANCES_DELETE
9 RSALERTPROC
10 RSWWWIDE
11 RSBCS_REORG
12 RSALERTCONS
Together with a functional consultant you can determine the variants for these jobs.
Hope this helps.
Best regards, Marco
