Yes, it is possible.
Look at "DemoTabControlA2002.mdb" (attachment, zip).
There you can see 3 tables, (tblMain, Table1, Table2), 3 forms,
MainForm (with 2 tabs) linked on the tblMain, Subform1 linked on
the Table1, and Subform2 linked on the Table2.
Look at the "Relationships".
Subform1 and Subform2 are linked with MainForm via "Link Child Fields" and
"Link Master Fields" properties, (fID, f1Num and fID, f2Num).
Adapt it in your mdb.
