You can define or edit the areas of the data source to share with the data target in a partition. An area is a subcube within a database and a partition comprises one or more areas. For example, an area could be all Measures at the lowest level for Actual data in the Eastern region.
When you define a replicated area, ensure that the data source and data target contain the same number of cells. The shape of the two partitions must match. For example, if the area in the data source covers 18 cells, the data target should contain an area covering 18 cells into which to put those values. The cell count does not include the cells of attribute dimensions.
You can use substitution variables in a partition area definition, which provides flexibility in sharing different data at different times. See Substitution Variables in Partition Definitions.
