Screen exit in badi FTR_CUSTOMER_EXTENT for tcode FTR_EDIT

Hi,

I need to add new tab to standard screen interest rate instrument (SAP t-code FTR_EDIT). In the new tab i need to add input parameter to save customised field in table vtbfha. I'm using SAP ECC6.

When searching for any user exit or badi, i found out badi FTR_CUSTOMER_EXTENT. There is no sample code that i can refer to.

I've looked at that BaDi and there is an option to add FCodes and Subscreen.

Is there possiblities that we can add new tab and input parameter to the standard screen.

How can i proceed from there.

Kindly help.

Thanks,

Biah
