how to report on links between DNG requirements and RQM test execution steps in a global configuration context

Hi,
I'm getting problems to export a document with a test execution result which have links between its steps and requirements in a DNG module.

I tried with the following data of the schema with no result:
feed/entry/content/executionresult/StepResults/StepResult/requirement
feed/entry/content/testscript/steps/step/requirement

I provided the related global configuration context on my sources which seems to work because I tried to execute another testcase in another configuration and I don't have it in my document generation.

Last but not least I tried to follow the different answers given in previous questions, it works until I enable configuration management in Doors Next Generation and Rational Quality manager...

Please help
