Most SAP customers are going through their year end processing. In the fixed assets area I wanted to highlight two blogs we already have on SDN that provide excellent material on this process.
The first Year-End-Closing in Asset Accounting (best practices) covers a step by step process on how to carry out the closing process.
The second Detailed Information on Changing the Fiscal Year in FI-AA has information on the fiscal year change program RAJAWE00.
I'd also like to highlight that now is a great time to recalculate the values in the subledger. It is highly recommended that the recalculate program (RAAFAR00) be run before running depreciation for the final time in your production system. This program helps ensure that all values used in reporting and depreciation are correct and accurately reflect the current configuration and master data settings in the system. The program documentation is worth reading as is OSS note 139666.
To execute the program you can use the menu path / transaction code shown below.
You should execute the program in test mode for your relevant companies. Like most SAP programs in FI-AA it has to be run in the background in order to analyze all of the assets in the database.
