PO, PR, GRN with selected WBS as per depertment

Hi,

I am a PS consultant. In our current WBS we only maintain Responsible Person as per Depertmant HOD, CO Area , Business Area, Co Code, Plant. (This are common for all WBS). There is only one storage location & purchaseing group.

Now at the time for this Tcode ME51N,ML81N, MIGO, MIRO, we need the HOD can select only those WBS in which they are assigned as Person responsible. I don't know BASIS.

Please help me in this issue.

Rgds,
