When orders that qualify for rebate programs are invoiced, earned rebate entries are added to the Earned Rebate Credit Workbench form, so you can process credit amounts available for application with open credit memos.
To process earned rebates:
NOTE: If a rebate you need to process is not on the Pending tab, you can check the Hold tab to see if it has been placed on hold. If so, you can set the rebate back to Pending on the Earned Rebates form.
Open credit memos are created and the status of the earned rebated is changed to Applied.
