This looks complicated enough that it's probably fastest to resolve by opening a support ticket (PMR).

I don't know how this happened to you but as Daniel says raise a support ticket.

Now I see something similar (but not the same duplication of the system defined attribute values) when I do a ReqIF import and the artifact types in both the provider and consumer project have changed, and rather than a merge of the type system it creates a 2nd similar type, attribute, etc.

The duplication can also happen in V4.0.1 with import project properties from another project into one already containing the same types.

Now how do I resolve the duplication of the artifact types.

1. First I determine which artifact type I want to keep, and if necessary merge attributes.
2. If it is the "artifact type2", I use the grid view to show me all the artifacts of the "artifact type" and use the grid to change the attributes for all selected artifacts, and change them to "artifact type2"
3. After there are no more "artifact type" artifacts in the project, I delete this type from the project.
4. After the "artifact type" is deleted, I rename "artifact type2" to "artifact type"

I repeat this for all the type, attributes and data in the project.

Hi Robin,

I did import a project template from another RRC instance. And my initial thought was the same that the import might have caused it. After reading your comment I think that is the cause.

As per IBM, it could be related to following issue (one of the symptoms even though it does not explicitly mentioned)

My issue was resolved after rebooting the server as stated in the above URL. IBM has temp fix for this. And I think the fix is also available in 4.0.0.1 and 4.0.1.  I applied the temp fix.

Thanks!
