Informix Error -23524
-23524 CM error: Nested cogroups not supported.
A request to create one or more cogroups specified at least one cogroup member that is actually a cogroup, rather than a coserver. Cogroup nesting is not supported.
Determine which of the cogroup members specified are themselves cogroups, replace their names with valid coserver names, and resubmit the request.

Solutions / Resolution

Examples
