The following calculation logic applies if
The aggregate storage outline contains a time dimension or date-time dimension with one or more attribute or linked-attribute dimensions.
You perform queries on time balance tagged measures.
If the above cases are both true, MDX Aggregate() semantics are used to evaluate the cells.
For example, consider a scenario in which:
Year is a time-date dimension with a day level hierarchy.
Holiday is an attribute dimension on Year, with each date tagged with Holiday_TRUE or Holiday_FALSE.
Opening Inventory is tagged as TBFirst.
The value of (Year, Holiday_TRUE, [Opening Inventory]) is evaluated according to the following MDX logic:
Aggregate( {Set of dates that are holidays in Year}, [Opening Inventory])
