XOLAP has the following restrictions:
No editing of an XOLAP cube is allowed. If you wish to modify an outline, you must, instead, create a new outline in Essbase Studio. XOLAP operations will not automatically incorporate any changes in the structures and the contents of the dimension tables after an outline is created.
When derived text measures are used in cube schemas to build an Essbase model, XOLAP is not available for the model.
XOLAP can be used only with aggregate storage. The database is automatically duplicate-member enabled.
XOLAP supports dimensions that do not have a corresponding schema-mapping in the catalog; however, in such dimensions, only one member can be a stored member.
