ECC TO SIMPLE FINANCE MIGRATION STEPS
Upgrade Paths
Suggested Migration Sequence
- Start migration without transports in separate copy of productive environment
- Start migration in Development environment
- Copy productive environment to test environment and import customizing requests from development system
- Migrate test environment, correct the errors found directly in Production environment.
- Repeat step 3 and 4 and test migration again
- Migrate productive environment after successful test migration
Migration from New G/L perspective
- Simple Finance Add-on is very similar to New G/L in terms of the functionality
- It provides the same capabilities as new G/L
- It is further optimized for SAP HANA i.e. No totals and index tables, convergence with CO, better reporting etc.
Migration from Classic G/L
- Following scenarios are not supported
- Document Splitting
- Balance Sheet at Profit Center level
- Ledger approach based Parallel Accounting
- Segment Reporting
- Addition of Customer Fields
Following scenarios are supported
Reconciliation between Financial Accounting and Controlling
Cost of Sales Accounting – No separate COS ledger needed
Change Management
- Have a good understanding of full scope, not just technical description of required customizing and migration
- Train end-users on delta part
- Have a time schedule that allow many test migrations
- Check authorizations during acceptance tests
- Involve auditors or compliance experts
Duration of Migration Project
Not Possible to make exact statement
Factors that can affect the duration are
- Support from customer
- Experience of project members and consultants
- Quality of Data
- Size of system
Test migration is the best input for calculation of duration and potential challenges during the migration project
Preparation for FI, CO
- Ensure all Balance have been carried forward for the current fiscal year
- Execute Delta upload to SAP BW for Account based CO-PA
- In case of Classic G/L: Initialize valuation differences from currency valuation. Field BSEG_BDIFF in open items has to be empty over all years
- If not, create a new valuation method and reset valuation before installation of Simple Finance Add-on
- New Foreign currency valuation run after migration has to be in same period
- Pre Check for GL and CO settings for upgrade, SAP Note 2129306
Summary
- Preparation phase has to be given high importance as there are very few possibilities for correction after the installation of Simple Finance
- Involve all key stakeholders to verify data for the acceptance for migration
- Clean out all the inconsistencies between different sub-modules
