Cut Over Strategy – Transactional Data
Cutover Strategy
 A number of preparatory activities need to be carried out to make
smooth transition to a new operational system in the live production
environment.
 The Cutover Strategy seeks to
 explain the steps that need to be taken
 draw a schedule for the tasks and activities that need to be completed
before transition
 Specify pre-requisites and business decisions required to ensure a
smooth transition
Cutover Strategy - Transition
 Transition to SAP ECC involves
 Execution of all transaction processing from the Go-live date in
SAP ECC system
 Switching off all legacy systems for transaction processing from
start of Blackout Period
 Ensure no manual transactions are carried out during the
blackout period
Cutover Strategy - Prerequisites

Pre-requisites for Transition
 System Configurations complete
 System Testing, Roles & Authorisations, End User Training Complete
 Ensure all the number ranges for all the modules have been maintained in the
production system
 Training for Super users and end users completed
 Upload tools wherever applicable are tested and ready
 Transfer/creation of all necessary master data in SAP ECC system (Material
Masters, BOM, Routings, Vendor, Customer, Operation and Collection Bank
,GL Accounts, Employee Master)
Cutover Strategy – Business Decisions
 Some important Business Decisions required
 Stages and levels at which open documents need to be taken
over in SAP ECC system
 Data that are go-live critical and non-go-live critical
 Assessing resource requirements and allocation of resources to
supplement efforts of the core team
 Recognising limitations on historical data availability
 Reconciliation of open items with General Ledger
 Feasible dates for cessation of operation in business critical areas
Cutover Strategy – Business Decisions
 Black out Period

business activities for a few days in order to control the switch
over process and steer the organisation to its new roadmap in the
ERP environment.

Project Systems – Internal Projects
Budget
•
•
•
•
Entire Capital Budget shall be maintained in SAP
For Project’s Budget, it is suggested to use ‘Plan Version’ in SAP to capture budget for the total life of
the project. (In SAP, there can be different Plan versions for different purposes but availability control
works on ‘Budget’ figures only)
In SAP, budget for the Project shall be entered for only; as in SAP, Investment programs for year shall
be created. No history of Capex or Opex budget shall be migrated to SAP.
For Projects started in fiscal year other than, no budget shall be entered for any period before 1st April---. (Plan version shall be used to capture the figures).
Actual Expense (Current Year)
•
Necessary accounting entries shall be posted using appropriate P&L Accounts at WBS element or
network element level
•
Other side of the entry will be to a P&L Clearing Account in respective profit centre; offsetting entry will
clear the expenses in P&L Account (Clearing P&L Account will not be a cost element).
Project Systems – Internal Projects
Actual Expense (Previous Year)
•
•
•
Consolidated accounting entry shall be posted for the total amount of expenses by using a ‘dummy P&L
account’.
This account shall be defined as ‘exempt from budget check’ and shall be used only for posting
historical cost on the job.
Once these costs are posted, this account shall be blocked. Other side of the entry will be to a P&L
Clearing Account in respective profit centre; offsetting entry will clear the expenses in P&L Account
(Clearing P&L Account will not be a cost element).
WIP
•
•
•
As total historical cost has been posted on the project as at cut-off date, project will be settled to
respective asset under construction. At AUC level, it may not be possible to know cost of each type (by
cost element) as costs incurred in previous financial years have been migrated using a ‘dummy P&L
account’.
At the time of capitalisation of asset from AUC, user will have to refer project cost report for defining
settlement rule. Based on the defined settlement rules, balance shall be transferred from AUC to final
asset
This exercise need to be done only for migrated projects. For Projects started in SAP, this shall not be
necessary.
Plant Maintenance
Open Notifications
