How to create a new Table based on Values in Slicer

Hello Community, 

I have created a new table from another table. and i want to get a value based on seleceted value on slicer. 

The slicer called Situation. 

In the new table i want to bing ALL  the values from MR/365 based on selected value from Situation. 

So basiclly as the Situation changes in the slicer i need th data in MR/365 change accordingly. 

This is the new table: 

This is MR/365 ( it's a calculated measure): 

MR/365= DATEDIFF (SELECTCOLUMNS(TC,"SITUATION",SELECTEDVALUE(TC[Situation])),SELECTCOLUMNS(BTA_Output,"Maturite",BTA_Output[Maturite]) ,DAY)/365

Thanks.
