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.
