What causes this issue?

Only a limited number of tables can be combined for a database
selection. Since the fields of one table are grouped together in a user
group, you are also restricted to a limited number of different user
groups for a selection.

System Response

If this number is exceeded, the database selection causes a runtime
error and processing is cancelled.

How to fix this error?

If you need to make a database selection that exceeds the maximum
number of combinable tables (user groups), divide your database
selection in two. Perform the first database selection, and then start
the second database selection using the result of the first.
