Question regarding BGP

Hi all,

I have a question regarding conditional injection of routes in BGP. We use
inject map and exist map for the same.
My doubt is whether a more specific route should exist in the IGP or the BGP
table coz wen we do simple aggregation in BGP there should be a specific to
that aggregate in the bgp table.

Please advise.
