Hi,
go and use trx POMA_BBP using "Purchaser Assignment" view for the PGroup.
Have a look into SAP Note 836262 for details.
After following the steps mentioned in the note, you will not find the purchaser´
assigned to the PGroup in PPOMA_BBP itself (where the default view would be
"Staff Assignment" view). The user would be still assigned to the other business
org unit. But in BUB3, when you display the available "Relationship" for the
purchaser's BP number, you would find a new "Is Employee of" relation to the
PGroup (in addition to the business org unit which the user already had). Then
the purchaser should be able to perform purchaser activities according to the role
assignment.
Cheers,
Claudia
