POWER BI DAX measure with filter, condition

Question

please could you help me with the below measure.

My table: query 1 The column “Indicator” contains unique number like, 119. MertricNumerator is my calculated filed by choosing option from slicer I want to get the result for Indicator number 119, then IF sum( numerator) is blank OR 0 or null “No Data” if Sum(numerator) < 5 show “low count of data” else SUM(Query1[Metric_Numerator]) Many Thanks

{ MEASURE= IF( SELECTEDVALUE(Query1[indicator])=119 && SUM(Query1[Metric_Numerator])<5, "Low count number", IF( SELECTEDVALUE(Query1[indicator])=119 && SUM(Query1[Metric_Numerator])=0 ||ISBLANK(SUM(Query1[Metric_Numerator])), "No Data", SUM(Query1[Metric_Numerator]) )) }

Answer 1

There are 2 things that doesn't allow you to get expected result.

1 - your second IF expression is a && b || c a && b || c . DAX engine doesn't understand how do you want to evaluate this expression - like (a && b) || c (a && b) || c or like a && (b || c) . DAX will evaluate the expression as (a && b) || c (a && b) || c , because && has higher priority level. Also, the expression is evaluated in the order that operators appears in the expression, from left to right. So, supply the expression with brackets.

2 - you want to get different data types from one expression - a string or number. It's needed to be corrected.

Please, check the corrected measure.

MEASURE = 
    IF(
       SELECTEDVALUE(Query1[indicator])=119 && SUM(Query1[Metric_Numerator])<5
       ,"Low count number"
       ,IF(
            SELECTEDVALUE(Query1[indicator])=119 
           && 
           (
            SUM(Query1[Metric_Numerator])=0 
           ||
            ISBLANK(SUM(Query1[Metric_Numerator]))
            )
           ,"No Data"
           ,"" & SUM(Query1[Metric_Numerator]) 
        )
)

This can work, but I would use SWITCH() instead.
