DAX for group by and datediff

Hi 

 

i have a table with 2 columns

 

 

id   start_date 

 

1     2017/05/06

2       ""

3       ""

4        ""

1    2018/06/05

1       ""

2        ""

 

Now I want to add a new column here which shows

a. The difference in start_date vs today ( I am able to achieve this using datediff function) 

b. I want to apply group by to 'id' column and take the latest date in the start_date column. In the above example for id=1 and start_date = 2018/06/05.  Once I am able to group by id and get the latest start_date for that id then I would find diff of it with today's date. 

 

Please help

Hi @rjain12,

Based on my test, you could refer to below formula:

Difference column:

Difference = DATEDIFF('Table1'[start_date],TODAY(),DAY)

Group by table:

Group by table = SUMMARIZE('Table1','Table1'[id],"Latest",CALCULATE(MAX('Table1'[start_date])))

Result:

You could also download the pbix file to have a view.
