Issue:
Users are experiencing an issue with customers when trying to edit the customer information. They are receiving an error that states that the registration code must be 6 hexadecimal digits.
Resolution:
When the customer is imported in from a third part application, some of them are coming in without their Registration Code generated.
To resolve the issue, generate the code by clicking the Generate new Registration Code button.
Once that is generated, make other changes to the customer and save. The error message will not appear again.
