Dynamic filters - Power BI

Question

I have the below dataset:

I need to calculate the number of accounts grouped by the datedif between today and first date per an account when type = 'cash'.

If I find the min date per account and type 'cash' using

first date = 
CALCULATE (
    MIN ( tbl[date] ),
    ALLEXCEPT ( tbl, tbl[account] ),tbl[type]="cash")

, I get:

And then, applying datedif to find the difference between today() and first date, I get:

The requirement, however, is not to hard-code the type. However, if I use the below formula:

first date = 
CALCULATE (
    MIN ( tbl[date] ),
    ALLEXCEPT ( tbl, tbl[account] ))

and then, 'cash' as a filter, I get the below result which is incorrect:

Answer 1

Hope this helps..

1. Change [Account] data type to Text.

2. First Date = CALCULATE(MIN('Table'[Date]), ALLEXCEPT('Table', 'Table'[Account], 'Table'[Type]))
