Windchill Relationtionship Report SQL SELECT

I would like to produce a Windchill relationship text-file report for all Pro/E CAD Documents (epmdocument), using an SQL SELECT statement (Oracle).

The output would include the following info:

DOCTYPE, NUMBER, Version, relationship-type, Related-DOCTYPE, Related-NUMBER, Related Version

Example output would be something like this:

ProE Versioned Part,12345.PRT,A.1,Associated Drawing,ProE Versioned Drawing,12345.DRW,B.5

I am slightly familiar with the tables epmdocumentmaster and epmdocument.
But I don't know which table (and fields) contains the relationship (where-used) data.

Any suggestions?
