Its because in source qualifier you can make the transformations like join, filter only with homogeneous sources like tables can only joined with tables. But if you have to join a file and a table then you have to use components like join and filter. Also some of transformations its better you do with the components as its faster and you can get proper logs and debug the issue.

Because of whenever we are getting data from tables then src_quli works, not for filedata
