Has anyone ever used dim rating with RateWare?

we are in the process of re-doing all of our rates as part of an SAP integration with SAP. Part of this integration requires recreation of all our rate offerings and records.

We have a break where DIM takes into place based on a cube. In the past we created a new offering and a new offering type, but this also mean that we had more offerings to maintain.

I am hoping to use a single offering and 2 records where the separation of the dim is done by volume in the rate geo cost. however, this does not appear to do the calculation.

the dim is at the rate geo cost and so is the flag that indicates dim pricing. the other record is set to no dim pricing. the dim factor is also at the rate geo cost.

any thoughts?
