L1 L2 L3 support: what each tier is actually allowed to do
The tier boundary decides your cost and your resolution profile, so we define it by action, not by seniority. Getting this written down is the single most useful hour of a scoping call.
- L1 — intake, triage, severity assignment, user guidance and resolution of known errors against a maintained runbook; no configuration change
- L2 — functional and configuration work inside the application: pricing procedures, workflow and approval routing, integration monitoring, master-data and authorisation fixes
- L3 — code and root cause: ABAP or CDS objects, Oracle PL/SQL and personalisations, Apex and flows, plus formal escalation into the vendor and management of the note or patch that follows
- A retained-organisation column, so the tickets your own team keeps are named rather than assumed
