DAX Formula help - conditional calculation

[ppgandhi11]

Hi, I have the first 2 columns, I want to computer the 3rd column based on the logic given in notes.  

ServiceCount is not a column. It is a measure that I have calculated correctly based on some calculation.

ServiceCount = count(LineItem)

Basically I have been trying something like:

ServiceLevelCompare = if(Service = "D01" || Service = "D02",

calculate(sum(ServiceCount), filter(master, Service in {"D01","D02"})),

if(Service = "D04" || Service = "D05",

calculate(sum(ServiceCount), filter(master, Service in {"D04","D05"})), "N/A"))

Above is only intended to get the sum part (denominator) in the calculation. Once we have that, the calc will need to just use divide function with numerator being ServiceCount.

No luck so far!  Thanks a lot!

I think this will help

ServiceLevelCompare = DIVIDE(ServiceData[ServiceCount],IF(ServiceData[Service] = "D01" || ServiceData[Service] = "D02",
CALCULATE(SUM(ServiceData[ServiceCount]),FILTER(ALL(ServiceData),ServiceData[Service]="D01"||ServiceData[Service]="D02")),

IF(ServiceData[Service] = "D04" || ServiceData[Service] = "D05",
CALCULATE(SUM(ServiceData[ServiceCount]),FILTER(ALL(ServiceData),ServiceData[Service]="D04"||ServiceData[Service]="D05")), 1)),0)

Thanks for the reply Arvind.  This does not compile. There is a syntax error in the beginning itself around the first IF condition.

... IF(ServiceData[Service] = "D01"  <-- this does not compile. The Service is not a measure it says.  The only available options are the measures of the context.

Have you tested it at your end by any chance?   

Thanks again.

I am able to get to below working which is not a complete solution, but it is first step in solution I believe.

ServiceLevelCompare = DIVIDE(Master[ServiceVolume-Provider], CALCULATE(count(Master[Line Item Number]),FILTER(ALLSELECTED(Master[Service]),Master[Service] = "D01" || Master[Service] = "D01")))

count(Master[Line Item Number] is basically sum of ServiceCount of D01 and D02 (100 + 200).

Master[ServiceVolume-Provider] is the numerator (100 for D01, 200 for D02).

Problem is: this is working only for D01 and D02. It produces correct result only for D01 and D02. For all others, it does not produce right result. it still divides for all rows with 100+200, which is incorrect.

I am unable to say that, For D01 - do this. For D02 - do this. For D03 - do something else.

I am still fairly new to power bi. So I am not sure how to get this done. Thanks.

Current output I am getting is with above formula:

Somehow I need to do the conditional calculation as shown in original post. Something like:

If(master[Service] = "D01" || master[Service] = "D02", <Do ServiceCount sum for D01 and D02>, N/A)  etc.

Hi @ppgandhi11

You may refer to below measure:

Measure  =
IF (
    MAX ( Table[Service] ) = "D01"
        || MAX ( Table[Service] ) = "D02",
    [ServiceCount]
        / CALCULATE (
            [ServiceCount],
            ALL ( Table[Service] ),
            Table[Service] IN { "D01", "D02" }
        )
)
