Description

Introduced in v3.14, this class prevents the overuse of Study Credits (beyond its available quantity) by students and guest users.

If a user:

• has REDU - Student or REDU - Guest permission, and,
   
• is increasing the Study Credit's ‘Used Quantity’ above its ‘Quantity’,
  
  
  • rio_ed__Study_Credit__r.rio_ed__Used_Quantity__c   >   rio_ed__Study_Credit__r.rio_ed__Quantity__c
     

then, the class will prevent it.

Note:

It only checks if students and guest users are using more Study Credits than the available quantity.

It does not prevent the admin user from doing the same.

Use case

When a student or guest user places an order for a Study Offering, they will need to pay the amount of the Order Line.

Study Credits can be used as a “voucher” to offset the amount.

But if there are limited Study Credits available for usage, the users should not be able to use more than the available quantity.
