BAPI_ACC_DOCUMENT_POST posting duplicate entries

[Former Member]

Hello,

I have been working on BAPI_ACC_DOCUMENT_POST bapi to create a WD application for creating an invoice similar to Tcode FB10. I finished doing the application with the help of the forum members apart from few issues. My issue is:-

The BAPI_ACC_DOCUMENT_POST" bapi is allowing the end user to make duplicate invoice payments which is not acceptable. We need the BAPI to return an error message if a duplicate entry exists. For eg:- If we enter a duplicate entry in FB10 it throws an error message telling the user that a duplicate entry exists. But, this is not happening in the case of the BAPI.

Could anyone help me in finding a way to check for duplicate invoice entries and throw an error message. I would greately appreciate your help.

Regards,

Your question doesn't really seem to be Web Dynpro ABAP/UI related. For questions on the usage of BAPIs or how to code the business logic of your application, you should ask those in the ABAP General Forum.
