ISINSCOPE DAX Function (Information)

Returns true when the specified column is the level in a hierarchy of levels.

Syntax

ISINSCOPE ( <ColumnName> )
Parameter Attributes Description
ColumnName

The column of the level.

Return values

Scalar A single boolean value.

Returns TRUE if the column is in included in the filter context and it is a grouping column for the current row in the result set.

Remarks

ISINSCOPE checks there is a filter placed on the column derived either from context transition or from a group by column placed by SUMMARIZECOLUMNS, which implies that there are only zero or one value in the current filter context.

When ISINSCOPE returns TRUE, HASONEVALUE might still return FALSE if there are no data for the intersection considered. This could happen in SUMMARIZECOLUMNS, as described in the Distinguishing HASONEVALUE from ISINSCOPE article.

Examples

--  ISINSCOPE is useful to detect if a column is currently
--  in the rows or columns of a visual (like groupby columns 
--  of SUMMARIZECOLUMNS) AND it has only one value visible

--  ISINSCOPE, like ALLSELECTED, deduces the information about
--  the grouping of a column from a different algorithm:
--  the column must show only one value in the filter context
--  and the filter must be coming from either a groupby column 
--  introduced by SUMMARIZECOLUMNS, or from a context transition.
--  Besides, the filter must be still active (not overridden)
