Turn the design decisions into a load sequence, a reconciliation harness built on the seven accounting controls the source names, and a rehearsed cutover that resolves staging, effective dating and commitment-control balances before the window opens.
The executive summary for this source draws a line that should govern the whole transition plan: core masters, calendars, terms, journals, assets and open balances are usually mechanical — after the target structure is approved.
The three structural controls are worth restating as a gate because they are the cheapest risk reduction on the programme.
The site's canonical wave model orders loads by dependency, and it maps cleanly onto the playbook's own staging for this source.
The playbook names seven accounting controls. Together they form the reconciliation harness, and each one should be automated and runnable on demand rather than produced by hand at the end.
The source, before extraction. The position the business signed off. The extract. What actually left the source, with the as-of rule recorded. The transformed set. What the mapping produced, after the crosswalk. The target, after load. What posted, queried from the target's own reporting.
In-flight staging. Rows sitting in Voucher Build or Billing Interface staging at the boundary have nowhere to go — the target has no equivalent structure. They are a cleanup task with a deadline and a named owner, and the deadline should be weeks before the freeze, not days.
The playbook names four controls that catch avoidable failures, and they are worth building into the load design rather than discovering during a mock.
A mock cutover that proves data can be loaded within the window proves the pipeline. The design is proven by something else.
The playbook names six key risks for this source. Five of them convert into transition checks.
The go and no-go criteria. Written before the rehearsal, in terms of the reconciliation controls rather than in terms of task completion. "The trial balance ties by GL business unit and ledger" is a criterion. "Data load complete" is a status.
Transition on a PeopleSoft programme is the workstream that enforces the condition the whole path depends on: structure first, then the mechanical work.
