ENDE technicians installing a prepaid smart meter in Luanda

Component 1 · Prototype environment

Powering Angola's prepaid electricity service, meter by meter.

ENDE field teams install, repair and commission prepaid smart meters across the provinces. This portal shows how those field events travel through SAP IS-U, SAP PI, ULTIMA PLUS and SAP ERP FI-GL — and where operators intervene when they do not.

About this prototype

Component 1 — SAP IS-U ↔ ULTIMA PLUS prepaid integration

The portal simulates the end-to-end prepaid integration between SAP IS-U, SAP PI, ULTIMA PLUS and SAP ERP FI-GL. Ten integration services carry customer, contract, installation, meter and vending events; operators can inspect payloads, reclassify errors, retry failures, send records to reconciliation and approve financial postings under maker-checker control. All figures come from a synthetic test dataset — there is no connection to a live SAP or ULTIMA PLUS system and no real customer data is used.

Integration transparency

Ten SAP IS-U ↔ ULTIMA PLUS services with communication IDs, retries and error classification.

Prepaid lifecycle

Customer, contract, installation and meter events traced from creation to vending.

Controls & audit

Maker-checker approvals, clearing references and a complete audit trail for every action.

Delivery scope

Front-end and SAP-side scope listed side by side, including open functional gaps.
