Unable to create Sales Order???

Hi All,

I am calling the BAPI_SALESORDER_CREATEFROMDAT1 to create Sales Order by passing the following values.

But getting an error "Please enter sold-to party or ship-to party.

If I execute the same BAPI by passing the sames values from SE37, I didn't get any error, it created the sales order.

Any one knows why this is happening?

Do I need to pass any additional parameters when I call this BAPI?

ORDER_HEADER_IN

-

DOC_TYPE

SALES_ORG

DISTR_CHAN

DIVISION

PURCH_NO

PURCH_DATE

ORDER_ITEMS_IN

-

ITM_NUMBER

MATERIAL

REQ_QTY

ORDER_PARTNERS

-

PARTN_ROLE

PARTN_NUMB

Thanks

Sundar
