You are creating a calculated measure in a sales cube by using a Multidimensional Expressions (MDX) calculation. The cube includes a date dimension. The date dimension has a hierarchy named Calendar…

Option A likely uses a hardcoded or less flexible approach such as YTD() without a proper hierarchy reference, which may not resolve correctly at all levels of the Calendar hierarchy.

The correct expression likely uses Aggregate(PeriodsToDate([Date].[Calendar].[Calendar Year])) or an equivalent that resolves the current slicer context dynamically. This approach leverages PeriodsToDate anchored to the Calendar Year level, which works whether the current context is Month or Day, making it portable across multiple levels of the Calendar hierarchy.

Option C likely omits the Aggregate wrapper or uses an incorrect period anchor, causing it to fail or return wrong results when evaluated at hierarchy levels other than the one explicitly referenced.

Option D likely uses a Sum or a fixed date range that does not adapt to the current slicer context, so it would fail to produce accurate YTD results at multiple hierarchy levels.
