Error
Solution
Create Background Job in SAP
You have to create background jobs for each program. I created one background job with sm37 tcode for example.
Tcode > SM36
You can create new background job for other programs for other errors.
Check Background Job in SAP
Tcode > SM37
Check Errors in RWB (Runtime Work Bench)
You can do repeat ping or page refresh to show new status.
You can see online status like below for all after added all background jobs.
Last Step : Schedule Jobs
You can get error in Business Process Engine in RWB (Runtime Work Bench). You can resolve that errors with below operations.
Tcode > SWU3
Tcode > SWF_XI_CUSTOMIZING
