Problem
The Centre availability field is not shown on the edit screen.
Possible cause
Centre availability can only be set when creating a discount code. It cannot be changed after the discount code has been created. This is a system limitation.
Solution
If you need the discount code available at different centres, create a new discount code with the correct centre selection.
You can deactivate the existing discount code by setting the Valid to date to today.
If the problem persists, contact support and include details about:
Which centres you need.
When the issue occurred.
