Need reference fields BAPI_SALESORDER_CREATEFROMDAT2

[prasad_dix]

Dear experts,

  I am using BAPI_SALESORDER_CREATEFROMDAT2  to create Sales Order. The SO has been creating successfully. However, certain fields are not getting added properly. I may be missing right elements to populate the data. 

I am looking for customer's purchase order reference field, Req.delivery date and plant. I tried with REF_1, PURCH_NO_C, REF_DOC for PO reference. But it's not working. For Req.delivery date and plant I am not able to find right fields.

Request to assist me in this.

Regards,

PD

I have tried with PURCH_NO_C and it's working for customer PO ref. However, If I try to re-run the same data to create SO it says, Sales order already exists.

Did you check if the data element of the screen field is the same as for the BAPI structure field ?
