Activating Aggregate causes short dump

Hello All,

I am working on the internal APO BW, trying to activate and fill the aggregates for infocube 9ADEMAND. When I try and do this, I receive a short dump and the aggregates remain unfilled, but active. The dump I am receiving is as follows:

Runtime Errors RAISE_EXCEPTION

ABAP Program SAPLRRSI

Application Component BW-BEX-OT

Exception condition "X_MESSAGE" raised.

Any help you can provide would be appreciated.
