You want to force the calculation context of a variable in a table so thatits values do not change when adimension is added to the table. Which of the following statements is correct?

The input context filters the rows considered before aggregation - including a dimension there would not fix the output aggregation level.

Excluding a dimension from the input context restricts which rows feed the calculation, which changes filtering behavior rather than fixing the aggregation granularity.

Including a dimension in the output context forces the variable to aggregate at a finer level, which is the opposite of the desired behavior.

The output context determines which dimensions a measure uses when aggregating. By explicitly excluding a dimension from the output context using syntax such as [Measure] In ([Dim1]), the variable ignores any additional dimensions added to the table, keeping its aggregated value fixed regardless of the table's structure.
