sort of a beginner here with using xml data source, but here I go:

I have one xml datasource with one table I am using.. however, I want to bring the table in twice and link them for logic purposes...

The issue is that when I attempt to link the tables, nothing happens.. no error messages or anything, just no link occurs. I will click on one field and drag it to it's corresponding field in the duplicated table.. after I let go, no link appears and that is it... any ideas why this can't be done?

data types are exactly the same.  All I am doing is adding a table in database expert by moving it over twice from data source to Selected tables.

is this the only solution?  I find my report to be really slow without doing the table to table link... or should that not make a difference?
