For each depreciation book, you must set up how you want the program needs to know how to handle various FA transactions for each of the FA posting types. For example, the program needs to know whether the posting should be a debit or credit and whether or not the posting types should be included in the depreciable basis or if it should be part of a gain or loss calculation.
You set this up in the FA Posting Type Setup window. To open this window, on the Depreciation card, click Depr. Book, FA Posting Type Setup. The program contains a default setup that can be used. You cannot insert or delete lines in this window; you can only modify the existing lines.
