Issue: 

Credit Memos for Points Rewards are Being Auto-Created after Customer has been Un-Enrolled from Program.



Resolution:

Points Reward Programs can be set up so that points are accrued through Sales/Service Orders. In this scenario, if the customer has accrued enough points, a Credit Memo will be awarded when the order is invoiced and paid. 

If a Credit Memo is awarded after the customer has been un-enrolled from the program, it is because the customer paid an invoice that was created when the customer was still enrolled in the program.
