PO net value

Hi,

I am trying to get the PO net value . me23n - header section - tab 'Conditions' - field 'Net'

on reading old threads i got some function modules

ME_FILL_KOMK_PO

ME_FILL_KOMP_PO

ME_DETERMINE_NET_PRICE

MM_NET_PRICE_CALCULATE

ME_GET_PRICE_CONDITION

ME_DETERMINE_SALES_PRICE

ME_PRICING_MARKET_PRICE

ME_SELECT_SOURCE_BY_PRICE

CALCULATE_TAX_ITEM

I am stil trying to figure out how to use these to get the PO Net value.

I am not MM functional, I am an ABAPer

Could you please give any guidance ?
