OLAP write back via formulas (functions), not read only pivot tab
 

Default OLAP Analysis Services access in Excel is read only pivot tables. Is
there a reasonably priced Excel add-in that allows MS OLAP Analysis Service
cube cell access via formulas (functions)? What I'm looking for is the way
Applix TM1 or Paris Technologies PowerOLAP works with "OLAPwrite" formulas
with their dedicated OLAP servers, but I want it to work with MS OLAP
Analysis Services. I am specifically looking for MS OLAP Analysis Services
Write Back to the cube to budget only scenarios while simultaneously
displaying Read Only Actuals. The pivot tables also have formatting problems
where the formulas retain formatting with no problems.
