Dear All,

I have requirement in Sales Order creation. Some condition get required on the basis of Partner Function entered in sales order .

I tried with one requirement development for pricing but i m not getting any data related to Partner function manually entered in Sales Order.

In KOMK structure i m getting only standard which is coming from process but not which one i entered (Account Number of Vendor or Creditor) .

Pl suggest how it is possible.

Thanks,
