Custom field in transaction REBDBU

Dear All,

Can you help us to get a custom filed in "General Data" tab in transaction REBDBU . We are using "Flexible Real Estate Management (RE-FX)".

I have already tried to get it through BTE , but unable to get the custom field defined even after all setting done in transaction FIBF( we have created custom Function Group and module by taking help of FVUFTMPL ).

Please help us.
