Ellucian's Q4 2025 Colleague update now strictly enforces the status field on the section-registrations API. DUAL-18897 addressed this for the registration workflow (New vs Add). IDEA-353 addresses the same class of problem for the drop workflow.
Colleague distinguishes three drop/withdraw status codes based on timing:
- Delete (X) — before class start date
- Drop (D) — during add/drop period (after class starts, before census)
