No connector found in Data federator administration tools

Hi All,

I would like to configure IDT to BW system using Relational Connection, I check the connection test in BW system by TR se37,

but when I connect to DFAT, any connector was found to configure it, and add the progIDMapping.

I would like to ask you if it is necessary to add this IdMapping in DFAT. or we have only to set this ID in IDT when creating the relational connection  to BW system.

For information: I used Business Object BI platform 4.1.

Thank you in advance for helping me.

Regards
