Zero Amount on Auto PO with catalog contract source

Hi Experts,

need some urgent help here.

we're implementing SRM7.0 enhp3 with MDM catalog3.0.

problem is, when I choose an item from catalog associated with a valid SRM contract, shown below

the Shopping cart gets the correct amount but the auto PO being generated upon ordring has zero amount, thus being put in SAVED status.

Contract reference from catalog line item as source of supply

we did some initial debugging and we came up with the conclusion that this happens when the price_origin field in line item data has value 'F'  - "automatic determination".

Any input/related info is greatly appreciated.

Thanks.
