Nothing is missing from your end. Its the standard functionality of the report it will filter the report based on the partner function or responsible person you have selected.( Sales order with that partner function available).
But it wont appear in the result screen.
No.I have not entered the person resonsible number in the selection screen.My basic business requirement is that on entering the SO number or the customer number in VA05N, it should give me the person resonsible field in the o/p screen.Which is not appearing at the momoent even if I enter the partner Function (ER).Though the field is present in the o/p layout but somehow seems like the system is not populating it.
The selction screen fileds are the filter parameters.I agree your point but being a part of o/p screen layout I think person responsible field should get populated on running the transaction.
