B470_PO_CREATE and BAPI_PO_CREATE and HEADER_TECH_FIELDS

Hi

We are using SRM 4.0 SP 13 and ECC 6.0

I am creating a PO from SRM using B470_PO_CREATE which calls FM BAPI_PO_CREATE in ECC.

But its creating a PO where Item price is picked from previous PO.

BAPI_PO_CREATE contains HEADER_TECH_FIELDS data structure which has a field called NO_PRICE_FROM_PO. (guessing it is the solution for no picking price from previous PO)

But I could not find HEADER_TECH_FIELDS data structure available in SRM FM B470_PO_CREATE

Has anyone used it or any suggestions?

Thanks,

Nikhil
