This topic provides information on the differences between aggregate storage and block storage databases with regard to attribute dimensions. To use the information in this topic, you should be familiar with attribute dimension concepts for block storage databases. See Working with Attributes.
The following information applies to attribute dimensions when used on aggregate storage databases:
Only the addition (+) consolidation operator is available for attribute dimensions.
For a given attribute dimension, all associations must be with one level of the base dimension. For example, in the ASOsamp.Sample database, associations for the Store Manager attribute dimension are with level 0 of the Stores dimension. The following restrictions apply to attribute associations:
Attribute dimensions do not have hierarchy types. You cannot specify an attribute dimension as a dynamic or stored hierarchy. Essbase treats attribute dimensions as stored alternate hierarchies of the base dimension. For example, in the ASOsamp.Sample database, Essbase treats the Store Manager attribute dimension as if the Store Manager dimension were a stored alternate hierarchy of the Stores dimension.
When using query tracking, Essbase considers queries on attribute dimension data and may include attribute dimension members in aggregate view selections. See Selecting Views Based on Usage and Calculating Aggregate Storage Databases.
