cost center assignment in IT 0001

Hi All,

I have a situation where master data is maintained in PA with active integratin with OM. However my client now wants to assign cost center at Organisational Unit level. When i tried this thru Relationship infotype in TCode PO10, i can't see the relevant cost center in IT 0001 Org Assgn.

Just wondering if I've missed any settings ?

An early reply shall be appreciated.

Regards
