Just believe what @LinusH and I are telling you. The EG integration into SAS Metadata is different from what you might think and it won't allow you to retrieve source to target metadata mapping from EG projects. This information is not stored in the SAS metadata server but in the actual client side EG project (.egp file). You can open such a .egp file with WinZip and then have a look into the XML's there.
Once the developers store the SAS code developed in EG as external .sas files the EG project keeps only the references (links) to these external files. It's these SAS scripts which you run in batch via a 3rd party scheduler.
On top of it: You can write dynamic code with SAS so which tables get used how is eventually data driven and only determined during run-time (and could even differ from execution to execution).
