To ensure that rebates are paid out only on invoices that have status paid, an admin can create a custom field in the Transaction Journal object, and copy the invoice status data from the source system into that field. Then, the admin can use that field as an eligibility condition in the Rebate Types, so that only transactions that match the criteria are included in the rebate calculation. This way, the admin can avoid paying rebates on invoices that are not yet paid, or that are canceled, refunded, or disputed.
