[SOLVED] Master Data Services 2016 data validation: Must be unique in combination

When I save my 'Must be unique in combination with following attributes' with 1, 2 or 3 other attributes, Master Data only saves the first attribute, as I had only choose a 'Must be unique independently'. Any idea? Bug in MDS 2016 SP1? Thanks for your advice.

I found the solution here : https://connect.microsoft.com/SQLServer/Feedback/Details/3112582

Microsoft tell us:

The fix for this issue is included in the following updates:

SQL Server 2016 SP1 MDS GDR https://support.microsoft.com/en-us/kb/3210089
... (I am limited with max 2 links in my answer!!!! grrrr)
...

I installed the KB and I upgraded my MDS database.

It solved all my problems with Business Rules :-)
