If they are all common to all CI types then you have to add them to BaseElement. Adding them to their own class wont show up in all the other classes.
I have implemented quite a few CMDBs now and found that the number of attributes does slow down the upgrade but nowhere near as much as actual data in the classes. My recommendation would be to really look to see if the attributes are needed on all classes. If so then you have no choice but to add them to the BaseElement.

Instead create your own custom Class and add those attributes to that class. Otherwise, your next upgrade will be a nightmare. _____ From: Alejandro Canon <aca...@extensionsa.com> To: arslist@ARSLIST.ORG Sent: Friday, July 22, 2011 10:57 AM Subject: Adding Custom Attributes to Base Element ** Listers, ARS 7.6.04 SP1 CMDB 7.6.04 ITSM 7.6.04 I need to add about ten (10) attributes (common to all kind of CIs) to BaseElement. I’ve read some threads (dated about 2009) recommending to NOT ADD attributes in Base Element Class, because of known errors in Asset – CMDB Sync process. What’s your experience about that? Understanding CDM Model is based in CIM Model I think there shouldn’t be problems in adding fields to Base Element class. Believe me if I’m telling you I’ve reviewed all BaseElement attributes from BMC.CORE and BMC.AM namespaces and I have no match for these 10 attributes required. I guess a known issue could be extense time you may have to wait after saving changes in CDM, because custom attributes in Base Element must be propagated to all subclasses.
