REP-586: Adding this data link will create a cycle.

Cause:

The group you specified as the parent group for the data link is not eligible to be a parent because it is, directly or indirectly, a child of the query to which you are linking it.

Action:

If possible, move the group such that it is not a child of the query and therefore eligible to be its parent group. Otherwise, there is no action you can take.
