"column cannot define a level in more than one dimension"
*Cause: A column was used in the definition of a level after it had
already been used to define a level in a different dimension.
*Action: Reorganize dimension levels and hierarchies into a single
dimension such that no column is used to define levels in
different dimensions. There is no limit on the number of
levels or hierarchies you can place in a dimension. A column can
be 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.
