Adding custom tab ( payment ) in the Rfx Response header

Hi Gurus,

I need to add the custom tab at the header level in the tab RFX Information of the RFX response application.

Please note that I am not asking for item level .

The following tabs are already present : Basic data , notes & documents , Table extensions , conditions.

I need to add payment tab . Is it a standard tab which can be configurable ?

Thanks in advance ,

Regards,

Abhishek.
