Report Builder Query on Requirements with an Attribute with no set value
I want to make a query to show me all artifacts in a DNG project with an artifact type of Requirement (across modules). I can get this part fine. Next I want to filter and only show those requirements with "no set value" in a certain attribute tied to that artifact type. It seems inconsistent depending on the attribute I select. TAGS for example have a "no set value" option. But I have another attribute called "VnV Method" that only list the values to select. There is no "no set value" option. This is in 6.0.3 ifix008 with LQE. I tried doing a "is not" option with selecting all but it does not give me the "no set value" results. Any guidance would be appreciated.
