Dynamic data masking from leaf to subscription not working as expected in MDS 2016

Hi,

While doing PoC for dynamic data masking in SQL 2016, We came across an issue, where we are trying to process data after applying mask function in one of the attribute in leaf table. When we process leaf data to subscription view as admin user, subscription procedure (UDF) reading mask data instead of original data & processing the same in MDS subscription.

Ideally if we are running MDF leaf UDF as admin user, it should process original data not masked one.

Is it MDS bug or Is there any other way to process the same?

Thanks,
