The Swap Form
Open the line's detail page, click Swap Line, and fill five fields. Source profile is the current owner. Destination profile is the new owner (pick from existing user profiles or create a new one inline). Device option: transfer, return, or BYOD. Effective date: today, next cycle, or custom. Notes field for any context the audit log should capture. Submit and the swap processes.
If the swap is immediate, the billing attribution changes within minutes. Usage alerts re-route to the new owner. Manager visibility updates on the dashboards (the destination's manager now sees the line). The source's profile shows the line as Transferred in its history with a link to the swap record. If effective-date is future, the swap holds in Scheduled state until the date.
