Conversion Program for Creating Loan Contract

Hi,

Has anyone worked on a conversion program to create a Loan Contract?

I am trying to use a BAPI. Its BAPI_LOAN_CONTRACT_CREATE.

But the problem is this BAPI is not released by SAP yet.

Can I use a BAPI which is not released. If YES, then what are the problems I would be facing later. And if NO, then what is the solution to this?

Thanks.
