Creating Customer using BAPI

Hi experts,

I am using BAPI_CUSTOMER_CREATEFROMDATA1 to create customers from portal.

We are using Search Term 1 and 2 fields in the transaction VD01 while creating customers from SAP GUI.

But I couldnt find these fields in any of the structures in this BAPI.

Is there any standard BAPI which can solve this issue?

Can anyone help me out?

Thanks alot in Advance
