Maintaining Depreciation Periods
For fixed assets you need to ensure that the required depreciation periods are available. When the software is installed, a range of depreciation periods are automatically populated and available to your establishment/organisation however, there may be occasions where additional depreciation periods are required.
This topic explains how to create and maintain depreciation periods stored within a keylist in IRIS Financials.
