ebs session and table relationship

I might have asked the same question before. But I couldn't find my old post anymore. If this is a duplicate, I apologize.

I understand that there is etrm.oracle.com site that lists all the ebs tables with the column description. However, my question is, if say for example, I am in an ebs session (gl for example), how can I tell from the session display and the data info to know which table in the ebs database is this session's info corresponding to? Please advise. Thank you very much.
