ONTAMS - Sr Oracle EBS Technical Specialist

Builds, unit-tests and deploys RICEFW components on Oracle EBS R12 across Procure-to-Pay and Order-to-Cash, for a contract-manufacturing and consignment process. Works from functional specs written by the SCM and Finance consultants, writes the technical design, and fixes defects through SIT and UAT under the Technical Lead.

Key responsibilities

1. Read functional specs (MD050), raise gaps with the functional consultants, and write technical designs (MD070), unit test plans and migration scripts.
2. Build PL/SQL packages, concurrent programs and request sets for P2P flows: requisition to PO, blanket purchase agreements and releases, ASL, receiving, consigned inventory from supplier (ownership transfer, consumption advice) and AP invoice creation.
3. Build O2C components: sales order import, pick-release and ship-confirm hooks, component-sale invoicing to contract manufacturers through AR AutoInvoice, and receipts reconciliation.
4. Build extensions such as the Clear-to-Build engine, shortage alert engine and reschedule publication, using Inventory, PO, WIP and BOM tables and public APIs.
5. Develop BI Publisher reports (data templates, RTF/Excel layouts, bursting), such as the consolidated contract-manufacturer inventory view and consigned aging.
6. Build and customise Oracle Workflow (PO approval, notifications) and AME rules where approvals change.
7. Run data conversions (open POs, BPAs, on-hand and consigned balances, item and supplier masters) through open interfaces and APIs, including mock loads and reconciliation reports.
8. Package objects with FNDLOAD, XDOLoader and migration scripts, hand them to the DBA for SIT, UAT and production, and support cutover.
9. Tune slow SQL and PL/SQL (explain plans, trace/TKPROF, indexing, bulk processing).
10. Fix SIT and UAT defects within agreed turnaround, and provide hypercare support for owned objects.
