Automatic Posting Config in MM On the Condition of Asset Acquisition

amit butola || 26 Aug 2013 12:46 pm || 6

Hi Guys,

I issued a purchase order by ME21N in the purpose of buying a fix asset,
then I receive my asset by MIGO ,but when I try to enter invoice by MIRO,
there is a error message as below:

I know there is something wrong with my configuration of the automatic posting in MM
but I don't know how to make the right configuration.

Account determination for entry A999 WRX CN01 not possible

Message no. M8147


The system did not find an account for this transaction. This means that
the account determination for key A999 WRX CN01 is not maintained in MM
Customizing (Valuation). The key is made up of:

o Chart of account

o Transaction key (= Posting transaction)

o Valuation grouping code

o Account grouping code
o Valuation class

System Response

Contact your system administrator.

    Hi Friend,

    Double click the transaction WRX
    Chart of accounts---CN01, press ENTRY
    Valuation class is empty.
    then, maintain the debit and credit accounts.
    Reopen MIRO, give a try.

    It is fine now, you are awsome !
    But, I don't understand why should the Valuation class be empty.

    Just according to the message "Account determination for entry A999 WRX CN01 not possible ", you can see there is no valuation class.
    You are buying an asset, PO account category is A. I want to know is there a material number in the PO? I guess material number is empty, and material group is not empty.
    If so, you should check IMG-MM-PUR-ACC.ASSIGNMENT-Assign default values for asset class.

    Hope it is helpful.

    Please check ME2O, enter the vendor and see if the material exist at the vendor premises.

    If does exist, you have to return back the material using MB1B (movt. 542, spec.stock O) enter the site, the vendor and the material. Once posted successfully you can try to do backflush.

    Thank you very much.

    Please check your entries in t-code : OBYC
    in OBYC goto Transaction key WRX (double click on this key)
    check here whether an entry for the G/L accounts for the Valuation Class of your corresponding material (MM03 Accounting view) exists.
    If an entry does not exist then you need to make an entry here.
    Hope this is useful.
