# Oracle EBS Discrete Manufacturing Go-Live Checklist > Source: https://netray.co/tools/oracle-ebs-discrete-manufacturing-go-live-checklist > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: Free Tools ## Short answer A grouped go-live checklist for Oracle Inventory, BOM, WIP and Cost Management covering setup, data, testing and cutover for discrete manufacturers. ## Category oracle ## Erp Oracle E-Business Suite ## Audience - Oracle EBS project manager - Oracle EBS consultant - Manufacturing IT lead ## Tool **Kind:** checklist **Groups:** #### Organization and item setup **Items:** **Text:** Inventory organizations created with correct master organization and calendar **Critical:** true **Text:** Item master attributes reviewed for each item template, including planning and costing flags **Critical:** true Units of measure and conversions loaded and approved Category sets and default categories assigned for inventory, costing and planning Subinventories, locators and nettable settings defined **Text:** Lot and serial control rules agreed per item class **Critical:** true Item revision control and numbering rules documented Transaction types and reasons configured, including any custom types #### BOM and routing **Items:** **Text:** Departments, resources and resource costs defined **Critical:** true Standard operations and routings loaded and validated **Text:** Bills of material loaded with effectivity dates and supply types **Critical:** true Phantom assemblies and option classes reviewed with engineering Engineering change process and approval workflow tested **Text:** BOM and routing import errors cleared with no unexplained rejects **Critical:** true Backflush and pull supply types verified against shop floor practice #### WIP and shop floor **Items:** **Text:** WIP parameters, accounting classes and default accounts set **Critical:** true **Text:** Job release, issue, move, completion and return flows tested end to end **Critical:** true Scrap, rework and negative issue rules agreed **Text:** Job closing and variance rules tested with sample jobs **Critical:** true Shop floor status codes and operation hold rules defined Barcode or mobile transaction devices tested if used Mass load and interface programs scheduled and monitored #### Costing and finance **Items:** **Text:** Costing method chosen and cost types defined **Critical:** true **Text:** Standard costs rolled up and reviewed, or average cost start values loaded **Critical:** true Inventory and WIP accounts mapped to the general ledger and tested Variance accounts and overhead absorption validated **Text:** Inventory accounting period opened and the close procedure rehearsed **Critical:** true **Text:** Opening balances reconciled between subledger and general ledger **Critical:** true #### Data, testing and cutover **Items:** **Text:** Opening onhand quantities counted, loaded and reconciled **Critical:** true **Text:** Open jobs, purchase orders and sales orders migrated with an agreed cutoff **Critical:** true Mock conversion run completed with timings and defect log **Text:** User acceptance test signed off by plant, planning and finance **Critical:** true Concurrent managers, transaction manager and cost processors confirmed running Roles, responsibilities and security reviewed for segregation of duties Training completed and super users assigned per shift **Text:** Rollback plan and hypercare support schedule published **Critical:** true **Scoring Note:** 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. ## Content **Intro:** 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. **Sections:** #### How to use the checklist **Body:** 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 **Body:** 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. **Bullets:** - 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 **Body:** 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 **Body:** 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. **Cta:** If you want help reviewing a plan like this or automating post go-live monitoring of interfaces and pending transactions, we can talk through options with your delivery partner. **Faq:** #### How long does an Oracle EBS discrete manufacturing go-live take? **Answer:** 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? **Answer:** 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? **Answer:** 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? **Answer:** 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. ## Search terms oracle ebs go live checklist, oracle discrete manufacturing implementation checklist, oracle wip setup checklist, oracle ebs cutover checklist manufacturing, oracle inventory bom wip go live, oracle ebs implementation checklist, oracle cost management go live --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
