SAP GRC AC 5.3 - MDM Integration ?

Hi SAP Experts.

First of all, I would like to know if it is possible to connect SAP GRC´s RAR module with MDM system. Previously, I read some information related with this:

In order to conclude, there is a possible way to connect if there is a PI Adapter and then launch the analysis like if I launch it to an Enterprise Portal. On the other hand, I have to create a specific conector.

That´s true?

Thanks in advance.

Regards.
