Finding days between project status changes

[ConnorH]

I have tried a number of things to try to make this work but I can not seem to figure it out. I have a project table which holds the created date for a project and a status table which holds status change dates and project status as a decimal. A project may have many different status changes.

My Goal is to find the time between the created date for a project and each status change. I am not sure if I need to use the project table or not considering the status tables contains the created date for the project. 

Project ID	Status Extract	Status Change Date	Created date
13568	3.0	7/15/20	7/10/20
13568	4.0	7/16/20	7/10/20
15598	1.0	7/18/20	7/16/20
15598	2.0	7/20/20	7/16/20
13568	3.0	7/20/20	7/10/20

Things to keep in mind: a project can go backwards or forward  with status changes, status Extract starts at 1.0 and ends a 4.0, and there is a Primary key on the status table. Product ID is the FK in the status table while it is the primary key in the product table.

I have tried a couple things. This is an example of one thing I have tried but it didn't work. 

Column = If(DISTINCTCOUNT('Status'[Status Extract])>1, DATEDIFF('Status'[Created], MAX(Project[Status Changed]),DAY), 0)

@ConnorH , What output you need. You have created date and status date with you, you can take a date diff.

new column = Datediff([created_date],[status change date],day)

In case you want to have diff with the previous record. refer to this
