Average of specific values

[Anonymous]

Hi Experts,

I have a question about Average

Please find the example file
https://gbil-my.sharepoint.com/:u:/p/simon_chung/EUq60XYA4PNMmqGFE61vGDwBT_lC2NT2ULIXPHYCtfIuEw?e=sD...

This is my formula

Average of A & B = 
    CALCULATE( AVERAGEX( 'Table',  IF('Table'[Code]="A", 1, IF('Table'[Code]="B", 2, BLANK()) ) ), 
    ALLEXCEPT( 'Table', 'Table'[Customer] ), 
    'Table'[Code] IN {"A", "B"} )

I want a Average of A & B, where A will assign as 1 and B as 2, by customer, the average will vary by selection of period.

but the result still can see that there are value for "other", how can I skip those values not A & B?

many thanks

Simon

HI @Anonymous 

Try this 

Average of A & B = 
VAR _code = {"A", "B"} 
RETURN 
IF(
    SELECTEDVALUE( 'Table'[Code]) IN _code,
    CALCULATE( 
        AVERAGEX( 'Table',  IF('Table'[Code]="A", 1, IF('Table'[Code]="B", 2, BLANK()) ) ), 
        ALLEXCEPT( 'Table', 'Table'[Customer] ), 
        'Table'[Code] IN _code
    )
)

Best Regards,
Mariusz
