Depends on how you're calling the report (using the OCX, DLL, or viewer executable). If you're using the OCX, the Master setting is for the master table, RelatedTables for the child tables. Look in the "Developing applications" section of the help file for a chapter on each way to call reports, and it includes a listing of the property names.
