IF function

[Anonymous]

Hi, I need help to calculate some sales but cannot work it out. 

Sample table as below: 

When "ranking by bill month" has value 1, all "invoice_amt" of "customer_id" is a "keep". The rest is not. 

I cannot figure out an IF function for this. Appreciate any help or advice!

Hi @Anonymous ,

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

Sample data:

Create below measure:

Measure = var a = CALCULATE(MAX('Table1'[id]),FILTER(ALL('Table1'),'Table1'[ranking by bill month]=1)) 
return IF(MAX('Table1'[id])=a,"Keep",BLANK())

Result:

hi @v-danhe-msft , thank you so much for your help. However, when I tried it with a larger data set, it does not work correctly the way I need it. The field "ranking by bill month" actually resets per "id"; so different "id" will have the same ranking structure. 

I tried your measure but it only works with id:2041. Basically, I just want to keep the "invoice_amt" of all "id" whenever the "id" has a 1 in the ranking by bill month". 

I hope I explain well enough. I am still learning Power BI as I go. 

I tried this measure below and it works now, credit to @v-jiascu-msft. I will test it for the whole data set. 

Measure =

IF (

    "1"

        IN CALCULATETABLE (

            VALUES ( Sheet1[ranking by bill month] ),

            ALLEXCEPT ( Sheet1, Sheet1[id])

        ),

    "Keep",

    "Not"

)

Thank you all,

Perhaps:

IF([ranking by bill month] = 1,[ranking by bill month],BLANK())

Hi @Greg_Deckler , thank you for your suggestion but this DAX only let me keep the "invoice_amt" of "customer_id" that has "ranking by bill month" =1; other "invoice_amt" of the same "customer_id" in this case will be blank. I need to include them all as long as a customer_id has a ranking 1 in their record.
