9r1 group members - can anyone help Roban?
we are just starting process of implementing Change Orders with 9r1 and PeopleSoft. wondering if you have worked this out, as we have similar environment? although, we are on PS 9.1, which is not yet certified - which version of PeopleSoft are you running?
I am not familiar with PeopleSoft Business Functions to be executed for Change/Cancel PO but would like to explain the general Approach for implementiing this requirement.
Your PO Source of Truth System will be Peoplesoft(PS) but the request to change PS PO can be done ONLY from Ariba since the PO got initiated from Ariba.And obviously you will require real time/batch integration between Ariba and PS for creating/updating the PO created in PS.
I hope this helps...
