Sapna,
The costing variant(OKKN) specifies how the externally processed operation is to be valuated. The costing variant refers to a valuation variant(OPN2). The valuation variant specifies the price used to valuate the external activity.
But when I am converting purchase req to purchase order an error' no components could be determined' occurred. How to resolve this error?
What is the business scenario you are working and you do not have any components in BOM for External Processing Operation Order Header material?
