How to create mass PO create Program through "BAPI_PO_CREATE1" for PO custom fields

[former_member798860]

I have created a custom program for mass PO creation through BAPI: 'BAPI_PO_CREATE1'.
There are some custom fields like- 1. ZNATPROC
2. ZTYPSUP
3. ZTYPSUP OF EKKO.

For these fields value is not populating for custom fields. I have correctly passed the values for these fields in Bapi through " extensionin" tab.

Thanks and regards
