To import other, more general or miscellaneous external dimensions select the Other Dimensions tab and perform these steps.
To import other dimensions:
Click Add. The Other Dimension List is displayed, identifying other external dimensions you can use.
Select the dimension to import. A row is added to the table.
From Dimension Depth, select the number of levels of data to import for the dimension. Zero (0) represents the root level.
Levels that you add in the future may require you to redefine the external data source to accommodate the levels. For example, if you select a highest depth of 3 for three levels, even if additional levels are added, only three levels are reported. However, the selection “No Restriction” returns values for all levels, and automatically adds any future extra levels.
