Yeah, Source will occupy memory. Source is the Member of an Source Physical File(SRCPF) which holds the records.
In AS400 everything will store in Database in form of Objects. Where as, Source will be stored as a member of Object(of type PF-SRC).

Does source occupies the memory space?
Everything brought into memory consumes memory space. Things that are stored on disk consume disk space (and when brought into memory, consume disk plus memory). Memory is also consumed by programs that allocate memory for their work spaces.
The question might need to be restated.
