If the buyer adds another line to the RFx that was not in the Shopping Cart, how will the additional line item be funded or approved by the requisitioner?

(1) If alternative item/substitute item/supplement line added to bid response, the system will adopt the account assignment information from the original line item. 

(2) If a new line item is added independently to a bid response, the funding needs to be entered by the Buyer at time of PO creation. This would also apply to scenarios in which the Buyer adds items to an RFx (when creating it). 

In both of the cases there is no workflow back to the SC approver - this needs to be managed through ad hoc approval as per business requirements.
