RPE 6.0.5 and DNG 6.0.4 - Data Sourse for Custom DNG Attributes

I have setup a Data Source for Text and module and I can report on DNG Title Attribute.  when I try to report Custom Attributes I do not get anything reported?  When I look at the Data Preview I can't see the Custom Attributes listed?

Any suggestions?..

I did search for Questions and answers on the Forum but it's difficult sometimes to find exactly what your issues is and also you have to guess which version etc. based on Date.

I had seen that link and tried the suggestions and a few others;  I think I'm struggling with RPE for Custom Attributes as I'm using Global Configuration...  I have looked on the DOORS Next Generation data sources..

I'm not able to add a Schema and then setup the Data Source and preview to see the Custom Attribute.  Unless the "Name" is not listed?

I'm using a standard Schema :   https://<server>/rm/publish/text?metadata=schema

I'm using the following Data Source:

URI :  http@//<server>/rm/resources /<URI>  (the URI is from DNG - first part of the long string of the URI)

Extra Header: Link: <http://jazz.net/ns/profile#POX>;rel="profile"

Configuration-Context *2:  https://<server>gc/configuration/<ID>

And OAuth authentication.

I have managed to report on the DNG data for built in attributes..  so something is working...

Thanks
