New GL and New Asset Accounting for S/4HANA Finance
From our current setup with classical GL and classical asset accounting in ECC, we aim to transition to S/4 HANA Finance by migrating from the existing ECC system.


From a perspective the we are using classical GL and classical asset accounting in ECC and we want to Migrate from existing ECC system to S/4 HANA Finance.
Generally a question arise if we are migrating to New GL with S/4HANA Finance then why should I run a separate project?
Here is the answer to this question.
In S/4 HANA Finance New Asset Accounting is must to use and for new asset accounting it is must to use New G/L. So how we can handle New GL in S/4 HANA Finance without proper migration from classical GL to New GL while migrating from ECC using classical GL to S/4 HANA Finance.
Two options has been given by SAP for this scenario:
1. Migrate from classical GL to New GL.
2. Migration to new General Ledger Accounting as part of the migration to the S/4 HANA Finance.
What is difference between these two options?
1. Migration from classical GL to New GL: This migration should be done as separate project and should be executed before migration to S/4 HANA Finance. With this migration new functionality get introduced like:
Document Splitting
Balance Sheets at the Profit Center Level
Parallel Accounting
Segment Reporting
Ledger Approach for Parallel Accounting
Custom field
2. Migration to new General Ledger Accounting as part of the migration to the S/4 HANA Finance.
For sake of migration to S/4 HANA Finance we activate New GL and this provide us minimal functionality of New GL. Migration to new General Ledger Accounting as part of the migration to the S/4 HANA Finance does not support major functionalities likes
Document Splitting
Balance Sheets at the Profit Center Level
Migration from Special Purpose Ledger to New General Ledger Accounting
Parallel Accounting
Segment Reporting
Ledger Approach for Parallel Accounting
custom field
We should migrate to New GL as separate project if we want character wise balance sheet. This migration can be done before migrating to S/4 HANA Finance or after migrating to S/4 HANA Finance but required separate project.
