v1.4 · operations platform

Allocate volume across racks. Publish to DTN. Stay out of the spreadsheet.

Terminal is the operations layer that sits between SAP / S/4 and DTN TABS. Operators schedule policy-driven runs, preview every override, and publish in one click — with audit, RBAC, and per-row tracking that holds up to a Big-4 walk-through.

01 / The problem

You shouldn’t be allocating volume in Excel.

The morning loop at most refined-fuel distributors looks the same. An ABAP export drops into SharePoint. Three Excel tabs get massaged. A 9am Teams call confirms which ship-tos are in scope. Someone pastes into the TAS Web form by hand. DTN rejects half a load and nobody knows why.

TodayABAP export → 3 Excel tabs → Teams call → copy-paste into TAS Web.TerminalOne policy. One preview. One publish. One audit log.
02 / Workflow

Four steps. One auditable cycle.

The same loop the operator runs every morning. Policy is the ground truth; everything downstream is derived and verifiable.

  1. STEP 01

    Define a policy

    Formula, ratable window, override rules, who can override. Versioned; previous policies stay queryable.

  2. STEP 02

    Generate a preview

    Per ship-to demand vs. available — calculated against current open volumes in under 2 seconds. No state mutation.

  3. STEP 03

    Approve overrides

    Row-level annotation. Every override carries an actor, a reason, and a timestamp — straight to the audit log.

  4. STEP 04

    Publish to DTN

    Idempotent write to TABS. The auto-reconciler watches the response and surfaces drift on the dashboard.

The boring, important parts. Done.

Per-row preview

Every ship-to gets a line. Diff against last cycle, overrides annotated, exportable to the controller before publish.

Signed audit trail

Append-only event log. Actor, subject, payload, occurred_at. Filtered views by ship-to, by operator, by reason code.

Admin, operator, viewer. Last-admin guard. Tenant_user.role surfaced everywhere the api enforces it.

04 / Proof
“We used to call a 9am Teams meeting just to confirm which ship-tos were in scope. Now everyone reads the run preview, comments inline, and the publish happens at 10:30. The meeting died.”
