ServiceNow Expeditions #11 - Business Rules - After

After Business Rules run after the record is written. They react to committed data: read what changed, touch related records, and kick off downstream work. Think of them as the “post-save” layer where you reconcile side effects you can’t safely do in Before.

✳ 𝐓𝐀𝐊𝐄𝐀𝐖𝐀𝐘𝐒 ✳

After rules run after the record is committed and should react to the saved state.

Use after rules to update or coordinate other records, and keep current-record preparation in before rules.

Do not call current.update() in an after rule because it can retrigger after rules and create loops.

Run only on relevant changes by using "changes" and tight conditions.

Dot-walk safely by guarding nulls and validating references with isValidRecord().

Offload follow-up work with gs.eventQueue() or Async rules so the transaction stays fast.

Keep logic short to avoid long-running transactions that block the user session.

Order your after rules deliberately so they don’t conflict with or undo each other.

Use previous vs current intentionally to detect what changed and drive your logic.
