NAV 2015 and MMR 2012

Hi All,

I am a newbie of NAV.
i know MMR (Microsoft Management Reporter) 2012 is a upgraded version of FRx which can work on many Management Report.

Did any of you used the MMR on connecting to NAV 2013 R2 or even NAV 2015?

I have did a trial on working on the MMR2012 to connect to NAV2015 as NAV DataMart. but failed with message below.

The Operation could not be completed due to a problem in the data provider framework.

I can connect to the NAV Database and it can get the company list from the database. but when i try to work on any report, this error prompted.

Did anyone know how to solve it?
or MMR is not supporting NAV?
