You want to force the calculation context for a variable in a large report with many dimensions. Which operator allows you to add a dimension to the default context?

The In operator restricts the calculation context to only the dimensions explicitly listed, rather than adding dimensions to an existing default context.

The All operator instructs WebI to use all available dimensions in the universe context, rather than selectively adding a specific dimension.

The ForAll operator removes specified dimensions from the calculation context, producing a less granular result rather than a more detailed one.

The ForEach operator forces a measure to be calculated at a more granular level by adding specified dimensions to the default output context. For example, using ForEach([Country]) on a sum forces that sum to be broken down per country, even in a block that does not include the Country dimension. This is the correct operator when you want to expand - not restrict - the calculation context.
