count attributes in a history table with multiple parallel entries

Hello friends,
I'm having difficulties creating a measure. I want to count the how manytimes a partner changed into different status.

The data looks like the following (Link pbix File) :

FACT_TABLE

DIM_ACTIVE

DIM_BANNED und DIM_DEACTIVATED contain different reasons, why a partner is banned and/or deactivated. A Partner could be banned or deactived for more than one reason at once (see line 1 & 2). Therefore multiple entries in the FACT_TABLE can be valid at once (Line 1 & 2, // 5 & 6).

I want to know how many different reasons (BANNED and DEACTIVATED) the Partner went through. Common DAX-Function such as COUNT(ID_DEACTIVATED) = 7 or DISTINCTCOUNT(ID_DEACTIVATED) = 3 are wrong, if you look at the data from a historical point of view:

The expected result is 4, as there a 4 times in history, where a new deactivation reason was added.

The expected result for banned reasons is 2. In total the Partner changed into 6 different reasons.

How do I create a measure like this?

Thanks in advance 🙂
