Promo-code scope locks and invalid-code checks

In GiveCampus Events, available controls depend on your permissions and the interface used by your institution.

For a complex event, Include event Add-Ons and Activities in discount extends the code's scope. The edit screen disables that control once the code has been applied to completed or reserved registrations. Do not assume it can simply be checked on an already-used code; support should assess a new correctly scoped code and existing registrations separately.

The apply action looks up the code case-insensitively within the current event's active date window and rejects it when its usage limit has been reached. No end date does not bypass a future start date, wrong event or usage cap. A registration holds one promo-code association; applying another replaces it rather than stacking two codes.

A 100% promo code records a discount, not proof that an offline payment was received. Do not use it as an accounting-equivalent substitute for a paid offline registration without reviewing reports, receipts and the institution's intended process.
