How do I create a % formula between fields

[PTSS]

Hi All,

I have a data format like this

Account Group Amount
Acc1 Group1 200
Acc2 Group1 400
Acc3 Group1 100
Acc4 Group1 300
Acc1 Group2 150
Acc2 Group2 600
Acc3 Group2 200
Acc4 Group2 200

I want to calculate the share between accounts in the image below

For Acc1 there is no need to do the calculation, for Acc2, Acc3... the calculation is always from Acc1.

The calculation is like in the picture column %

Help me for cases like this

Hi,

Please check the below picture and the attached pbix file.

Amount measure: = 
SUM( Data[Amount] )

Percent measure: =
VAR _acc1 =
    CALCULATE ( [Amount measure:], Account[Account] = "Acc1" )
VAR _amount = [Amount measure:]
RETURN
    IF (
        HASONEVALUE ( Account[Account] ) && HASONEVALUE ( 'Group'[Group] ),
        DIVIDE ( _acc1, _amount )
    )
