As of ActiveControl 8.3, it is now possible to customise the [Reason for Rejection] dropdown values that are seen in the Inbox/Outbox Rejection screen.
This has been added to allow Customers to tailor the default out-of-the-box values to terminology used within their own organisation.

Rejection Reasons can be maintained via transaction /n/BTI/TE_REJ_REASON in the Domain Controller.
Further details on how to configure this new capability are detailed in this online Change Note.
