As of ECC 6.0, it is already possible to use the new asset accounting (FI-AA new) in SAP ERP. The basis for this is the new general ledger accounting, and the activation of special business functions is also necessary. The new FI-AA solution is a further developed and simplified variant of the classic SAP module for asset accounting.
There are various scenarios for which the use of the new Asset Accounting already in ECC is particularly recommended. If you want to represent Asset Accounting in SAP for the first time, you should in any case activate the new solution directly. This will not only provide you with an improved or extended range of functions, but will also reduce the effort required during the upcoming S/4HANA migration.
During the migration, there will still be activities, but the scope of these activities will be much smaller if the new asset accounting has already been used in ECC. If you already use classic Asset Accounting in SAP, but want to post post postings in all valuations in real time, this is possible with the conversion to the new FI-AA.
The conversion to the new FI-AA solution brings two major simplifications and improvements. The depiction of parallel accounting principles or valuations using the delta posting logic has been simplified, making the need for delta valuation areas and restrictions regarding transaction types obsolete.
If you want to take advantage of the new Asset Accounting before the transformation to S/4HANA, you can already convert to the new Asset Accounting in ECC as part of a pre-project. However, the full range of functions of the new FI-AA is only available with the new data model in S/4HANA. To activate New Asset Accounting, the charts of depreciation must first be converted and adapted to the logic of New Asset Accounting. However, the existing business processes can be largely retained. Once the necessary adjustments have been made, the relevant conversion measures can begin. The changeover to the new asset accounting is client-wide. Once executed, the capitalization cannot be reversed. Therefore, a detailed analysis of your system and the individual components you are using is necessary in advance.
