used to define a level in a different dimension. Action: Reorganize dimensionlevels and hierarchies into a single dimension such
that no column is used to define levels in different dimensions. There is nolimit on
the number of levels or hierarchies you can place in a dimension. A column canbe
used to define any number of levels provided all such levels are in the same
dimension and provided no two levels contain identical sets of columns.
