Wrong patch advisory name in CLM filter

suppose you have to add a patch to your CLM for a monthly patch cycle.
To check what happens, I’ve used a filter type “Patch (Advisory name)”, but I’ve used for Advisory name a wrong name, like SUSE-12-SP8-2021-1494 ( SP8 does not exist absolutrly ). I’ve updated the filter and build again the project, but no error appears !!!
The filter correctly shows “IDONTEXIST: allow erratum equal SUSE-12-SP8-2021-1494 (advisory_name)”
How it is possibile ?? WHo checks the availability of the patch that I wrote ?? I’ll receive an error only when I’ll try to update the client linked to this project ???

Thanks a lot for any suggestion.
