SAP Message AC424 - Depreciation area &1 is already closed for the year &2.

Diagnosis
Processing terminated, since depreciation area &V1& in company codeV3 is already closed in fiscal year v2.
Area &V1& is linked, through a derived depreciation area, to otherareas that are still open for fiscal year &V2&.

System Response
You chose a function that can change the values in company code &V3&for the year &V2&. However, for this to work, fiscal year &V2& must beopen for all, or at least certain particular, areas. If the fiscal yearis only open for particular areas, you must ensure that the areaslinked with them through derived areas are also open. The rule here isthat either all the areas dependent on a derived area must be open, ornone of them.

Procedure
Check the last fiscal year closed for the individual depreciation areas(application menu: Periodic processing -> Fiscal year close).
