How the System Charges Back Costs

When you run the Charge Back Costs action from the Generate tab of the Chargeback Costs Wizard, the system does the following:

Checks to see if there are existing Scheduled Cost records from a previous invocation of this action. These are chargeback costs that have been generated but not yet approved; their Cost Status is AUTO-ROLLUP OR AUTO-PRORATE. The system asks if you want to delete these records; the action is canceled if you decline to delete them. This ensures that the Scheduled Costs table always holds the result of only a single chargeback calculation - the last time the Charge Back Costs action was run.
Updates area totals so that the chargeback uses the most up-to-date area data. The system also updates prorated areas for suites, groups, or rooms, depending on your chosen Lease Area Method (set with the Select Lease Area Method task). The system determines percentage responsibilities for common areas, which are then rolled up to leases.
For costs that are charged back to leases, checking if any chargeback cost agreements apply to the rolled up/prorated costs, and adjusting the chargeback if necessary.
Creates new Scheduled Cost records for the newly rolled up and prorated chargeback costs. These records have a Cost Status of AUTO-ROLLUP or AUTO-CHARGEBACK.

AUTO-ROLLUP costs are assigned to the item in the Rolls Up To portion of the Assigned To - Rolls Up To - Prorates To field.
AUTO-CHARGEBACK costs records are assigned to the item in the prorated portion of the field.
Completes the Amount - Expense or Amount - Income with the rolled up/prorated amount.
Completes the Date Due field with the latest date found in the Date Due field of the Costs records that were grouped together for roll up or proration.
The Date Transaction Created field is set with the system date.
The Cost Description field is completed with a memo documenting the rolled-up/prorated cost.
