Field help (EDPRBAS) 

This field displays the depreciation basis to reverse if necessary.
When there are several events on the current fiscal year, only the first event contains this information. It is possible to select another event which will contain the depreciation basis, by right-clicking on Allocate the balance sheet amount, called from the line of the selected event.
SEEINFO If the previous totals reversal is requested, these totals will also be contained in the selected event and not in the first one.
