Hello David,
Apologies for this not having been responded to in a long time. Do your questions here remain without answers?
I think the questions here center around a key point many users miss.
While under the Data Source Inventory for an integrated Data Source like Spectrum show all Groups Spectrum has configured, its common to see what appears to be incorrect group membership when looking in CAPM vs. Spectrum.
I suspect it has to do with what devices are, or are not, synced to CAPM via the integration.
Pick a group in Spectrum that is synced to PM and seen in the Data Source Inventory for the Spectrum Data Source. Pick one that has expected membership in Spectrum but none, or incomplete members, listed in CAPM.
Now look in the CAPM Domain based GC in Spectrum devices synced to CAPM are being added to. Do all device models present in the Spectrum group, but missing from the PM representation of that group, exist in the domain based GC used to sync devices?
Thanks,
Mike
