PART OF THE EBS → FUSION CASE STUDY

    EBS → Oracle Fusion Migration: Challenges & How We Solved Them

    Real Oracle EBS-to-Fusion migrations are won or lost in the details. Here are the challenges this programme threw up across 18 business units — and how the Syntra ETL platform absorbed each one.

    18-business-unit assignment

    Items and supplier sites had to be assigned correctly across 18 BUs. Solution: the BU logic was encoded once in Syntra and applied consistently to every record, instead of being re-derived by hand each run.

    🗂️

    Master-data gaps

    Mandatory fields were missing — supplier category type/class, the L1–L5 category hierarchy, several classification fields. Solution: load-readiness checks surfaced every gap in staging so PwC could source or default values before import.

    🔤

    Reference-data normalization

    Bank/branch names differed only by case or spacing between source and Fusion (e.g. “Main branch” vs “MAIN BRANCH”); classifications needed codes, not text. Solution: normalized and mapped to the Fusion masters and value sets in the tool.

    🧱

    Transactional integrity

    Agreements with headers but no lines get silently dropped; duplicate document numbers and inactive document styles cause rejects. Solution: header/line keys kept consistent, duplicates made safe via batch keys, and styles re-pointed to active Fusion values.

    🧹

    Source data quality

    Unescaped special characters, over-length values and non-numeric values in numeric fields broke imports. Solution: caught and cleaned in staging, with the pattern fixed in the tool so it didn’t recur.

    📎

    High-volume attachments

    Seven-plus object types carried attachments into UCM, with MIME, size and parent-linking pitfalls. Solution: validated attachment integrity and linked each file to its parent record, proven at volume across the full-volume main runs.

    ♻️

    Repeated re-loads

    Loading the same records across mock and production cycles risks “already exists” collisions. Solution: idempotent loads with batch keys and de-duplication made every re-run safe and traceable.

    🔐

    PII in non-prod

    Real contact data can’t sprawl through test environments. Solution: sensitive fields were masked for non-prod loads, and supplier-contact user accounts were not created.

    🤝

    Multi-party governance

    Syntra had no direct line to the end customer — everything routed through PwC. Solution: a single operational interface, spec-freeze per milestone, and a written audit trail of every input and sign-off.

    The through-line

    Every one of these was absorbed the same way: validate against the Fusion target before loading, encode transformations once in the tool, make re-runs idempotent, and reconcile every object. That is what turned a messy, 18-BU EBS estate into a clean, auditable Oracle Fusion cutover — about five times faster than doing it by hand.

    Frequently asked questions

    What was the single biggest technical challenge?

    Consistency across 18 business units — item-to-BU and supplier-site-to-BU assignment — combined with master-data gaps. Encoding the BU logic in the tool and validating against the Fusion targets before load addressed both.

    How were repeated mock and production loads kept clean?

    Loads were idempotent: batch keys and de-duplication meant reloading the same records never produced duplicates or “already exists” errors.

    How was sensitive data protected in test environments?

    PII such as contact phone and email was masked for non-prod loads, and no user accounts were created for supplier contacts.
