Hi Geeta,
I am also quite new to PA and I find the direction above quite interesting. I believe you would have gone through the post below:
Introducing SAP Predictive Analytics 2.0!
It says, PA is built on Lumira Codebase. There are two posts by SAM that talks about SAP MII and Lumira integration.
SAP MII, HANA/ESP, and Lumira (Business)
So I believe there is a way we can read MII from PA as well. I would still wait for other experts to comment on this.
Best Regards,
Swaroop
