Deleted Depreciation Plan

In the previous FY users somehow managed to delete Depr'n Plans for all subsequent FY's.

The action was apparently prompted by a Log Reading generated from 'Status of Contexts/ Posting Tab / Depreciation charges not posted', indicating that they should run the Account Interface for Accounting Entry Type FASCNL, which of course if only for deleted assets.

My problem is to re-create the missing plans for the current and subsequent FY's, so we can generate depreciation charges.

Does anyone have any constructive suggestions.

Thank you in anticipation.
