I've had the same experience as Victor noted. I've added them with no problem - did need to work them forward through the joins.
The only thing I'll add is to watch Field ID's. If the field ID that is used (generated or otherwise) is also used in another form feeding the same join, the field ID of one of those items on the join can change. If that happens and you build workflow to process the field, it can have some type mismatch issues (ie one is an integer and the other a date field). At least that's what we've seen. ----- Original Message ----- From: "Victor Olufowobi" <[email protected]> To: [email protected] Sent: Friday, July 22, 2011 2:21:23 PM Subject: Re: Adding Custom Attributes to Base Element ** Since these attributes need to apply to all further subclasses I don't think creating a custom class is a good idea. I have added a few attributes myself to Base Element without any issues. The time needed for the attributes to propagate to all existing subclasses depends on your system and the number of subclasses you have. You still need to modify the AST forms for the new attributes to be available in the required classes. Victor. On Fri 22/07/11 18:11 , "Alejandro Canon" [email protected] sent: ** John, Thanks for your recommendation. That custom class you mention should be a subclass of Base Element (BE), right? I´m asking that because I don’t see how a custom subclass of Base Element can propagate attributes to all existing subclasses in CDM. I was thinking creating a custom namespace and adding attributes in BE but stored in custom namespace. Alejandro.

Instead create your own custom Class and add those attributes to that class. Otherwise, your next upgrade will be a nightmare. From: Alejandro Canon To: [email protected] 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.
