Problems in RRC- RPE integration

Hi All,

Our team is working on RRC - RPE integration.
We are facing following issues:

1. How do we use our own RPE templates for generating reports in RRC?
In RRC under 'Other reporting options' we found a way where we can provide path for our own RPE template. When we select the template it asks for user authentication. We tried using user credentials which we use while login to RRC project but we are unable to add the external templates using these credentials.

2. Can we modify the inbuilt RPE templates provided on RRC server and use them to generate RRC reports? If yes kindly provide the steps.

3. Issue in data source for comments: In data source schemas under ' artifact/content/comment ' we are getting only '_value' here and not other attributes like author, plaintext etc. I have used following URI while adding data source for comments:
https:// <server>:<port>/rdm/publish/comments?metadata=schema

4. While generating RPE document using dynamic data source for comments many times we are getting 'HTTP/1.1 500 Internal Server Error'.

Please provide us solution for these issues.

Thanks in advance.

Regards,
Amol
