R/3 used to offer a way for you to access FI’s Asset Accounting customizing with a single transaction code, ORFA. In fact, it was the traditional approach to customizing the asset subledger. As of release 3.0, the Implementation Guide (IMG) became the preferred approach to R/3 customizing, but the old menu based ORFA was still available.
With release 3.0D, SAP stopped maintaining ORFA and eliminated it completely with release 4.0B. ORFA returned in a limited form with release 4.5 due to response from the Asset Accounting user community, but was not updated when 4.6 was released.
In spite of all these changes, there is still a way to bring back ORFA functionality and directly access the customizing for Asset Accounting. All it takes is some investigation and an SAP-delivered function module.
