Hi Preeti
Can you please post more information with screen shots? We're not all experts in all tcodes. :)
Also, you can look for OK codes, hit the F1 key on a field on the screen you are on and click to see technical details

double click on the status field

expand the sections = usually the lower section has the most.

It won't have every OK code, but it has many.
Best Regards,
Sigrid
