With the introduction of S/4HANA, the new asset accounting becomes mandatory in financial accounting; classic asset accounting is no longer supported. By combining the new FI-AA
with the new data model under S/4HANA, the full scope of the new solution is available, including extended functionalities and simplifications in the application.
The basis of the new asset accounting is the new, simplified data model based on the HANA database. Actual data, which was previously stored in separate tables, is now stored in aggregated form in the ACDOCA. Due to the new document logic, which
involves a merging of asset and general ledger document, some FI-AA document tables are also no longer required. Furthermore, the reconciliation effort between Asset Accounting and General Ledger is reduced due to the real-time integration of all depreciation areas.
In addition to the advantages of the new Asset Accounting that already exist in the ECC, the full potential of the new Asset Accounting component is available in S/4HANA. The new database provides the basis for further refinements and simplifications.
During the migration to S/4HANA and the associated conversion of Asset Accounting, a distinction is made between two possible initial scenarios. These are decisive for the required (transformation) steps.
If you are currently using classic Asset Accounting, there are some important preparatory activities to be carried out before the changeover. Since the new FI-AA component requires the new General Ledger, the changeover to it must be completed. In addition, the preparatory activities include the adjustment and migration of the chart of depreciation, the migration of documents,
and the execution of periodic asset postings. In addition, non-active company codes must be archived or migrated. After all these precautions have been taken and checked, the conversion to S/4HANA can take place, followed by the migration of the asset accounting
If you already use the new AA in ECC, there are only a few necessary conversion steps when switching to S/4HANA. Since you are already working with the new component, the business processes can be retained, only minor changes result from the changed data model on which S/4HANA is based. After you have completed the preparatory steps for the migration, check the requirements for conversion and
data migration using the tool provided by SAP. This is followed by the installation of S/4HANA, followed by the import of relevant settings. After successful execution, the migration to New Asset Accounting can be carried out and the FI-AA Customizing settings can be imported.
