Help Using datediff as slicer

[Anonymous]

Hello, I have this formula I want to replicate from tableau to Powerbi

The values there comes from two different tables, One is JIRA_FEATURES and the second one is JIRA_TAREAS.

It is supposed to work as a slicer 

I tried replicating it but I cant get it to work.

Could someone help me?

Thanks!

@Anonymous , can you clarify what exactly is not working?

The formula itself is not giving me any results, I dont know if it has to be because of the relationship between those two tables, that is many to many

XDIF FEATURES VS TAREAS =

DATEDIFF(SELECTEDVALUE(JIRA_INGENIERIA_FEATURES[FIN FEATURE]), JIRA_INGENIERIA_TAREAS[FIN TAREA], DAY) -> That is the formula im using
