How to add attributes in Jazz Report Builder

Please be more specific on your question. For example, you might mean any of the following:

1. How do I add a defined attribute (one I can select in RB) as a column of a report?
2. How do I add a condition on a defined attribute (one I can select in RB) to a report?
3. How do I define a new attribute in a data owning application so that I can select it when defining a report (such as #1 or #2 above)?
   

One thing to remember is that if you add custom properties in a domain application such as DOORS Next, ETM etc, you have to refresh the associated RB data source in Report Builder in order for the Type System Model to include it, or wait for as long as (default) 12 hours for the automatic refresh of a data source to occur.
