UNIT_PRICE, BASE_UNIT_PRICE and LIST_PRICE_PER_UNIT; how different are they and how are they populat

Hi Team,

Could you please help me out with understanding the the difference between the following three fields at the PO line level?

UNIT_PRICE, BASE_UNIT_PRICE and LIST_PRICE_PER_UNIT.

We would also like to know how different they are in the context of Purchasing Agreements i.e. BPA/CPAs.

I guess UNIT_PRICE comes into picture when the document refers to a CPA, and there are no price references and the unit price is keyed in.

But the concept of base_unit_price and list_price_per_unit can be a but misleading.

Kind regards,

Arun
