Key Concept

Transaction AS91 is a manual online transfer method of loading legacy data. It enables you to load the asset’s master data and historical financial data. It allows you to see how the loaded data appears in the master data, depreciation areas, and asset values screens of the asset. You can see the impact of different asset parameters, such as depreciation key and useful life on planned depreciation in SAP. It also is helpful in the design phase of the data conversion to assist in the mapping of legacy data to the asset master record. Other options for loading legacy data include Legacy System Migration Workbench (LSMW) using Business Application Programming Interface (BAPI), recording, direct input, or batch input; Computer Aided Test Tool (CATT); or the Excel migration tool (transaction AS100).

In an SAP Asset Accounting (FI-AA) implementation project, one of the main steps is the conversion of legacy data. This can present challenges such as mapping legacy data to SAP, understanding the effect of the take-over date used, and converting multiple currency data. I use the manual online transfer, transaction AS91, which enables me to load legacy data manually, and is very useful in addressing these issues.

Using this transaction can highlight the impact of customization activity in preparation for an automated data transfer using one of the numerous SAP-provided tools, such as batch and direct input programs. I’ll show you how to use transaction AS91, look at issues relating to different take-over dates, and provide some tips.
