   Leftover calculation for breakdowns

   The cost lines generated for the amounts coming to the segment indirectly from other segments, which are not part of a breakdown relationship with the segment, or by direct bucket allocations to the segment are the leftovers.

   If you want to calculate the leftovers for a breakdown, then set the system property com.glide.financial_management.generate_breakdown_leftovers to true.

   Run On Demand Only

   Use the option to generate the cost lines breakdowns on demand. This option helps in optimal usage of the allocation engine runtime.
