Countx within context transition

Hi All,

I am struggling with a context transition problem.

I have preapared a simple data model to illustrate it.

I have:

- 1 transaction table with values that I need to aggregate (in this table there are transactions id with duplicates)

- 1 date table with an active relationship (date_1) and an inactive relationship (date_2)

- 1 table with a list of values (from 1 to 500+) which will be used as an axis (an inactive relationship has been created between the transaction table and this table.

I want to count the number of occurences (values in the transcation table) and display the number of occurences on a bar chart using the 3rd table as axis.

The challenge is:

1/ to ignore duplicates

2/ to apply the right filter context (date_2 instead of date_1)

The problem I have is that my measure first applies a filter on date_1 and only then on date_2.

In the attached pbix, my measure is the following ("Count value (w/o dupliactes & based on date_2)". With the current filters on the report page the result should be 7 and not 6. One of the transactions is not taken into account because the "date_1" of this transcation is <> 2020.

How can I remove the filter context on date_1 and apply it on date_2 only? Please take a look at the attached file because the measure also use TREATAS to link the values from the transcation table and the axis table which makes the scenario a bit more complex.

Thanks in advance for your help.
