Oracle Error Message
ORA-36621: (XSAGMODDIM02) You cannot AGGREGATE the individual partition using static model workspace object because a partition dimension or its deriver workspace object appears in the equation of the step or simultaneous block.
Reason for the Error

Solution
AGGREGATE the variable instead of the individual partition.
