A current limitation in Power BI SWITCH measures (and all Power Pivot actually) is that a SWITCH measure must have a single format. It is currently not possible to conditionally format the measure result based on any criteria - it is one single format only. There are valid use cases where you may want to change the format of the SWITCH measure depending on the result. Consider the following SWITCH statement
myMeasure = SUMX(MeasureTable,switch([selected measure],
1,[Total Sales],
2,[Total Cost],
3,[Total Margin],
4,[Chg Sales vs LY %]
))
The first 3 results are all currency format, but the last result is a percentage format. This currently can't be controlled. I would like to see an optional 3rd parameter in the SWITCH statement to set an alternate number format.

Dynamic format strings are available in calculation groups and can be used to create a DAX expression to handle any format requirement for a pick a measure scenario such as this.

Documentation for dynamic format strings is available at https://docs.microsoft.com/analysis-services/tabular-models/calculation-groups?view=asallproducts-allversions#dynamic-format-strings-for-currency-conversion. And information on external tools to add calculation groups is available at https://aka.ms/externaltools.

There are multiple ways to utilize calculation groups and dynamic format strings and thank you to those who posted solutions in the chat.

You can use calculation groups but that is well in the weeds for most developers. I would love this functionality straight out of Power BI desktop.

You can achieve multiple formatting using Calculation Group -

Create Calc Group instead of SWITCH measure (and a disjointed table)  and define the Formatting to be applied for each measure return. It works perfectly well.

This would be very useful when working with multi currency data sources with multi currency options in the end report. SWITCH and FORMAT works for tabular display of data, but doesn't work with charts which do not seem to be able to handle the output as a number.

Please add a feature in Power BI to fix this problem.

I want to make my data currency with 0 decimals if $ is selected in a slicer but currency with 2 decimals if $ per widget is selected in the slicer. In order for a Matrix to automatically filter out Nulls, the format needs to be in a number format (Not Text).

I guess Calculation Groups now allows this.

I have read all comments in this tread and here is mine opinion:

1. Improved FORMAT() function could be solution, if this function would provide correct datatype & formatting. Not text as is now. (why, see Conditional formatting, Charts and etc.)
Master Measure:= IF(SelectedValue(Slicer[Value])=1, FORMAT([Measure1], "0,00"), FORMAT([Measure2], "0,0%"))

2. Solution could be to implement logic of inherent (parent) property in Measure tools => Format => (General, Currency, ...., Parent format).
It can be allowed only in case of stand-alone(pure) measure re-reference within IF(), SWITCH():
Master Measure:= IF(SelectedValue(Slicer[Value])=1,[Measure1], [Measure2])
In case of following := [Measure1] + [Measure2] - or similar, it should produce simple: Error in resolving parent formatting. Please select correct one.

3. What we then get (Yes, it’s more view & user experience):
3.1. Usage of Master Measure (MM) (which combines many measures (kpi) with help of IF()/SWITCH());
3.1. With help of slicer/visual in report user can select kpi in other visuals with MM (MM "reacts" on selected value in slicer);
3.2. In combination with parameter table(even sub-model) - where all measures of MM are listed - it’s possible to create:
a) groups and lists of kpi's / master kpi and child kpi's of group (off/on) / custom drilldown
b) user in slicer(if slicer and visual are based on parameter table field) can select needed kpi's, preferred layout, group of kpi's (depends on parameter table and slicer(s) in report);
c) parameter table allows to set kpi's allowed to see for the user (it is "row-level-security for the measure", especially if report visuals use only MM);
d) once report is developed, in some cases kpi's can be changed/added only with changes in MM and in parameter table.

I'm sure, other can add more ...
Hope, this will help us to get this nice feature faster! Vote !!!

Hi,

this is excellent idea. Must have for PowerBI.

One of the great Idea

Hi - this can now be done although it is a bit complex and has some limits.
