Write-ups are used for correction of depreciation values calculated in
the past (closed fiscal years). It is not possible to post write-ups to
assets that have been acquired within the current year. If you attempt
this, you will receive error AA402. Please review the R/3 Library
documentation for further information. The documentation describes the
procedure for write-ups as well as the two situations where write-ups
can be used.
A write-up is generally understood to be a later change to the valuation
of an asset. This change can take different forms, depending on the
reasons for the change. A write up can only be posted, if there are
accumulated values on an asset, it means the posting of a write up
corrects the depreciation from the past.
For example - The value adjustments (depreciation) that you calculated
in the past were too high. You must now correct this error using a
write-up in the current fiscal year. You can only post a write up, if an
asset has accumulated values.
But again the write-up functionality is designed to change prior year
asset not current year acquired ones.
If manual changes are necessary it may be possible for you to use
transactions ABMA - Manual depreciation or ABAA - Unplanned depreciation
to correct the depreciation amount.
Open the new fisical year and do the write-up from the previous fisical year
If want to post a negative unplanned value. Copy 640/650 to a zXX transaction type and set debit posting.
