Erro AA660 Net Book Value,

Hi Experts,

I'm facing an issue that I think I know how to solve it but I'm lost about finding the reason why I have it.

My usser is trying to post one unplanned depreciation of 579,584 trhough transaction ABBA on an asset with the following values:

Acq Vl: 11,591,678

Dep10: 5,276,522 (posted)

Dep'10: 6,930,421 (planned for the year)

Dep'11: 4,539,378

Dep'12: 118,692

Dep'13: 3,104

Dep'14: 81

Dep'15: 2

Dep start: 31/7

First Acqui: 31/09

It asset is transferred from another. Even when the Dep start is 31/07 the real depreciations started on 31/10 and this is why the customer would like to force the unplanned depreciations.

I do not understand why the system is giving error message AA660 Transaction in area XX contradicts the net book value . Should we run any procedure? What should I check?

For unplanned depreciations in OADB negative and zero values are allowed. I do not understand the reason.

thanks in advance.

    Hi Adela,

    1) Note 1143507:


    This error only occurs if the fixed asset has an acquiring transfer that

    is needed to ensure that the net book value remains positive once the

    manually-posted depreciation is taken into account. You posted this

    transfer with a reference date later than period 1. The system therefore

    only takes the transfer into account from the month of the reference

    date. For the manual depreciation, the depreciation calculation program

    evaluates the period control of the acquisition posting. This means that

    the program takes the manual depreciation into account from the start of

    the year.If no acquisition of at least the value of the manual

    depreciation document is available and the fixed asset/area only permits

    positive net book values, the system rejects the manual depreciation


    To fix the problem,please Change the period control of the MANU key as


    -Acquisition following years 06

    -Acquisition 06

    -Retirement 02

    -Transfer 06

    With this period control, the depreciation calculation program takes

    transfers into account from the start of the year.


    (Please also see note 50761 Unplanned and regular depreciation)

    2) 976573 AA 660 w/ manual depreciation, incorrect ANLC values

    3) In a few situations the solution is to allow negative values (AS02, OADB)

    Regards Bernhard
