Mark,

Wouldn't you have relations from the parent table to the three child tables in stead of the other way around?

select parent
set relation to key into Child1
set relation to key into Child2
set relation to key into Child3

>I have created an index on the (updated correction:) parent cursor, and issued "SET RELATION TO Log_ID INTO ParentCursor" for all 3 child cursors. The Target Alias for the first detail band is set to the name of the parent cursor. The Target Alias for the 2nd, 3rd, and 4th detail bands are set to the appropriate aliases of the child cursors.
>
>I still get the "alias not related to the current work area" error message. I have made sure my parent table is the current workarea when I try to run the report. If I remove all the Target Aliases, the report runs but I only get 1 record in each band. What am I missing?

>TIA!
