CM topology services doesn't display topology view for user defined group. however the "system defined " group dispaly the topology view. this wasn't the case on old LMS 2.6 but with LMS 3.2 we have this issue. did we miss something on setup/configration?
1. Yes, there is a procedure to drop the OGS tables from the cmf database, but you need to contact TAC to get this procedure. It is rather involved. This should be a last resort as you will lose all your user-defined groups. However, if there is a problem with the OGS configuration in the database, this procedure will correct it.
2. Externally, there is no difference between creating groups in Campus or Common Services. You can just use different attributes. Internally, groups to evaluate a group created in Common Services, the CampusOGSServer sends a message to the CSOGSServer which actually evaluates the group against the DCR tables in the cmf database. The CSOGSServer then returns a list of DCR IDs to Campus. If those same DCR IDs are managed by Campus, then Campus will display those devices on the map, and in device selectors.
