Here are guidelines to keep in mind when working with dimensions in Advanced Relational Access:
Advanced Relational Access does not support recursive dimensions/hierarchies.
Alternate hierarchies in standard dimensions are not allowed.
When a dimension is enabled for relational storage, Integration Server builds only to the dimension level. All members of the dimension are accessed directly from the relational data source.
For the accounts dimension, no hierarchy is supported. All members should be of generation 2.
