The EKKO-BSART proof type distinguishes the different types of requirement and order in the SAP system. The objective of framework agreements is usually to set a ceiling or a total volume (i.e. a target). For quantitative contracts, this is very specific to individual materials and therefore often to a material number (box: EKPO_MATNR), because.B this is where the number of parts or units plays an important role (even if there are other possibilities for an unknown material or consumer, but I will not come back to it here). For this reason, the reference value must be found at the level of the contractual position, because the target quantity (box: EKPO_KTMNG) multiplied by the price of each material gives the reference value (box EKPO_ZWERT) of each position. For value contracts, the quantity of items is often secondary, as the total value of the order matters.
