"Punchout" in iProcurement - Need to know a way by which the Line Type (in Requisitions) could be de

Hi Experts,

I need to know a way by which - we could have Line Types in Requisitions DEFAULTED as per the item categories selected by raising a requisitions for the same supplier. To elaborate more, for the same supplier we raise requisitions with categories that are for both Goods and Services. For categories which pertains to a service - the line type should default to Services - No Receipts likewise for Goods.

I tried a way by -

1. Updating an already defined Store with Supplier name

2. Added Smart Forms and associated the Categories with appropriate Line Types (in iProc we say - Item Type).
