These days, I read documents related with M8 system messages , tolerances , invoice reduction etc.

In this document , i work on implementation and configuration SAP MM Logistic Invoice Verification. My example contains a example which it prevents different postings based on quantity and amount. We will get a problem that i want to post bigger amount, sap will not give permission with error messages finally invoice reduction will solve our this problem.

I have a PO , my person posted a material document 100 qty.

     In Miro , can you post more quantities and amounts ? Is it related your tolerances ? Not at all.

     If posting exceed your tolerances , you can post but it is blocked. If not, you can not prevent. Sometimes , you can not be aware of tolerances when you can post fastly. It is dangerous.

Examples :

1 – Amount is bigger than PO.

2- Quantity and amount are bigger than migo and po values.

     What can i do ?

     Firstly , check your LIV system messages.

     You can update your M8 / 81-82-83-504 messages with ERROR also if you get them.

     * Please check DQ and PP tolerance keys.

     However , it is not enough to prevent posting . You have to maintain your LIV system messages.

     * I configure M8 messages with ERROR.

     * When i post our invoices , sap will not give permission…

     ** Unfortunately , i have to post some like a weigher result , vendor errors invoices with variances , how can i solve this problem ?

     **Sometimes , you can post your invoices with tolerance even though you implement system messages. Invoice reduction can help you.

     *Select layout : Invoice reduction , Correction ID : 2 Vendor error – reduce invoice ,Invoice amount Acc to Vendor , however you can use similiar way for quantities. Sap will create one more fi record for differences.

    ** Configurations :

     You have to configure your T030 table with RKA transaction (OBYC tcode) and invoice document types.

     I add RK document type for invoice reduction. (OMR4)

b2.JPG

     However, if you want to update some datas to implement in your country like a tax rates ..

     You have to update records with enhancement implementation program LMRMCF07 .

     EXIT_SAPLMRMC_001 -> include ZXM08U19

     I hope that it can be benefical for your business life thoughts.

     Thanks a lot for spending times …

    Hi,

       Good attempt!!!

       It will be good if you could include the following points..

    1. How / which tolerance key will work if you maintain GR based IV in PO and if its not maintained.

    2. There are other tolerance keys also in OMR6, what are the use of other tolerance keys and when these will be triggered.

    Regards,

    AKPT

          Hi Leo;

          You can benefit this scenerio when you get invoice in miro greater grn or amount. For example ; Invoice must be 10 $ , but you get it 11$ . If you implement invoice reduction , you can post credit 1$ to your customer as soon as you can post incoming invoice. However, good receipt is 5 pc x 1$ when invoice quantity 6 pc x 1$ . If you want , you can post 1$ when you post incoming invoice.

          About Bapi, we have to research. This is a special layout, i quess that there are different bapi. I will research.

          Thanks your valuable feedback.

          Regards.

    Hi all !! Thanks for this explanation! It´s really good! Please, someone can tell me, how can I check quantity tolerance in MIRO when I do the invoice without goods receipt? My PO has “GR-based IV ” indicator as ” “. So, I have not MIGO document, in MIRO I can do an invoice for a quantity larger than the PO and the system not blocked the document. Tolerance DQ need the goods receipt to work. If I put a larger price ammount, the system check that with PP tolerance and I can´t save the document, but I can´t find how to check the same for quantity. Thanks in advance!! Florencia.
