Hi,
Pick ekko-knumv, and use this to find out all pricing conditions from table KONV using condition ekko-knumv = konv-knumv. Then ask your functional guy to identify which all 'Condition Type" amount you need.
How it works is :
Every sales/purchase document has header data and item data.
Header data is that which is common to all item data.
EKKO is header data for Purchase document (it will hold data such as Vendor code, Doc date, PO Number - all these are common to all items in PO). One such field in Header is Document condition number - KNUMV.
Table KONV holds all condition types and its values for a condition number (knumv), all you really need to do is identify condition types and then pick up the values, so that really eliminates most part of manual calculations.
Hope it helps.
Regards,
KS
