Why Subledger Accounting is Fusion's defining accounting primitive with no D365 equivalent, what the Fusion ≠ EBS distinction means for the programme, and how the event → intent → voucher → ledger pipeline maps across the two systems.

Name the three heavyweight workstreams that dominate a Fusion programme
Introduction
Oracle Fusion Cloud ERP and Dynamics 365 Finance & Operations each turn the same operational reality — goods received, invoices approved, projects billed, assets depreciated — into audit-ready accounting. Both do it correctly.
Fusion ≠ E-Business Suite
Teams arriving with Oracle E-Business Suite experience will find that Fusion has moved substantially beyond EBS in several architectural areas. Applying an EBS migration playbook to a Fusion programme will miss the dominant workstreams — a gap that typically surfaces during accounting-translation sprints, six months into the project.
The pipeline both systems share
Both systems run the same four-stage pipeline. Naming it explicitly gives the whole team — architecture, finance, data, and programme management — a shared frame for every subsequent conversation.
The three heavyweight workstreams
Three workstreams consistently dominate effort in a Fusion programme. They are not sequential — they run in parallel and must all be in flight before any data-loading wave begins.
What this means for the programme
SLA translation starts on day one. It cannot be deferred to configuration sprints. The posting-profile design is a prerequisite for every functional test in every wave; no wave can be called complete until its posting profiles produce accounting equivalent to the Fusion SLA configuration.

Summary
Oracle Fusion Cloud ERP and D365 F&O both produce correct, audit-defensible accounting. They do it through different architectural choices, and a migration re-projects one set of choices onto the other.
