Adding a dynamic calc member increases aggregation time for strange reasosn

     Hello Community,

I am adding a Dynamic calc member(X_T) in my outline which is intended to be  X * -1;

This si increasing my time for aggregation from 10 mins to close to an hour. I understand that Dynamic calc members do not create blocks and hence do not increase aggregation time. But I fail to understand the reason for this exponential increase in time.

The script for Aggregation is

SET MSG Summary;

SET UPDATECALC OFF;

SET CALCPARALLEL 8;

SET CACHE HIGH;

SET LOCKBLOCK HIGH;

SET AGGMISSG ON;
