Oracle EBS Discrete Manufacturing Go-Live Checklist
A discrete manufacturing go-live in Oracle EBS touches Inventory, Bills of Material, WIP and Cost Management at once. This checklist groups the checks into setup, data, testing and cutover so nothing is left to memory on the weekend.
0 of 36 items complete
17 critical items still open - these are the highest-risk gaps.
Organization and item setup
BOM and routing
WIP and shop floor
Costing and finance
Data, testing and cutover
Aim to close every critical item before cutover. Unchecked non-critical items should have an owner and a date in the first weeks of hypercare.
Go-live plan review
Optional: ask an expert to review your Oracle EBS manufacturing cutover plan.
Optional. The tool and every export work without this. No spam.
How to use the checklist
Work through each group with the owner for that area, such as the inventory lead, engineering, the plant and finance. Tick items as they are demonstrated, not as they are promised. Critical items are the ones that, if missed, stop the plant shipping or block the first period close. Export the list to PDF or Excel for the steering committee.
Where go-lives usually fail
Most problems come from item master attributes that differ from the shop floor reality, BOM data that was never reviewed for supply types, and a costing setup nobody rehearsed through period close. Opening balances that do not reconcile between the subledger and the general ledger are the most common finance escalation in the first month.
- Item attributes set from templates nobody validated
- Backflush and pull supply types not matched to practice
- Close not rehearsed before go-live
- Opening balances not reconciled
Testing that matters
Run a full job life cycle with real parts: create, release, issue, move, complete, scrap, return and close, then review the accounting entries. Repeat with lot and serial controlled items. Run period close in a test instance and review pending transaction reports. Rehearse the conversion at least twice with timings so the cutover window is realistic.
Hypercare
Plan daily triage in the first two weeks, a monitored list of interface errors and pending transactions, and a rapid path to fix item and BOM data. Keep project resources available through the first period close, because that is when costing and reconciliation issues surface.
Frequently Asked Questions
How long does an Oracle EBS discrete manufacturing go-live take?
It depends on scope, number of organizations and data quality. Projects often run many months, with the cutover itself taking a weekend to a few days. Plan multiple mock conversions rather than relying on a single dry run.
What is the most common cause of a failed WIP close?
Jobs with unprocessed or uncosted transactions, missing accounting class setup, or variance accounts that were never tested. Rehearse job close and period close with real examples before go-live.
Should opening onhand come from a physical count?
Ideally yes, or from a reconciled cutoff count. Loading unverified quantities moves old inaccuracies into the new system and creates large adjustments after the first cycle counts.
Who should sign off the go-live?
Plant operations, planning, purchasing, finance and IT should each sign for their area. Finance sign-off should cover opening balances and the close procedure, because those items are hard to correct later.
