Hi,
You are right Pavan, In that case I would suggest you to check for a validation/substitution available for it in MM side.
Or
Go with development to validate it. Like if WBS is T-27-06-01 then G/L xxxxx should be picked.
Actually, I looked for one more option which is OKB9: Default account assignment ,here you can use network as account assignment under the WBS (exempt one) but I am not sure of it because it will bring account assignment with the entry of G/L and vice versa is possible or not,you can discuss on it with your FI/CO guy.
At last, its your call to decide which way to go.
Regards
Saurabh
