Applies to: Calculated column Calculated table Measure Visual calculation

Raises an error with an error message.

Syntax

ERROR(<text>)

Parameters

Term	Definition
text	A text string containing an error message.

Return value

None

Remarks

The ERROR function can be placed in a DAX expression anywhere a scalar value is expected.
This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules.

Example 1

The following DAX query:

DEFINE
MEASURE DimProduct[Measure] =
        IF(
            SELECTEDVALUE(DimProduct[Color]) = "Red",
            ERROR("red color encountered"),
            SELECTEDVALUE(DimProduct[Color])
        )
EVALUATE SUMMARIZECOLUMNS(DimProduct[Color], "Measure", [Measure])
ORDER BY [Color]

Fails and raises and error message containing "red color encountered".

Example 2

The following DAX query:

DEFINE
MEASURE DimProduct[Measure] =
        IF(
            SELECTEDVALUE(DimProduct[Color]) = "Magenta",
            ERROR("magenta color encountered"),
            SELECTEDVALUE(DimProduct[Color])
        )
EVALUATE SUMMARIZECOLUMNS(DimProduct[Color], "Measure", [Measure])
ORDER BY [Color]

Returns the following table:

DimProduct[Color]	[Measure]
Black	Black
Blue	Blue
Grey	Grey
Multi	Multi
NA	NA
Red	Red
Silver	Silver
Silver\Black	Silver\Black
White	White
Yellow	Yellow

Because Magenta is not one of the product colors, the ERROR function is not executed.
