Proble in Creating Multiple Item PO using BAPI_PO_CREATE1

Hi All..

I am creating PO using BAPI_PO_CREATE1. I have successfully created with single line item but when i tried to create with multiple line items it gives me error in partners(vendors) which i have used in table POPARTNER.

One more thing, I have created using BAPI with same partner roles with single line item but it gives me error in 2 or more line items.

So, Can Anybody help me in this..

Regards,
