    HI,

    Please refer the below OSS notes:-

    [https://websmp130.sap-ag.de/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/sapnotes/index2.htm?numm=356757]

    Summary

    Symptom

    When you try to post an invoice for the purchase order, the system generates error message M8783: 'Moving average price for material & & & is negative'.

    Additional key words

    MRHR, MR1M, MIRO, MMVAL, M8783

    Cause and prerequisites

    You posted a valuated goods receipt for a purchasing document for a material with moving average price control.When the invoice was posted (invoice item with price variance for goods receipt), the system generates error message M8783: 'Moving average price for material & & & is negative'.

    Between the posting of the original goods receipt and the entry of the invoice, the system already posted additional valuation-relevant transactions/events (goods movements, invoices and so on, can be displayed with Transaction MR51).

    The invoice verification tries (for stock coverage) to credit/subsequently debit the difference between the value of goods received and invoice item value for the stock.However, the material total value must not become negative by this stock posting.

    Solution

    Before you post the invoice, you must first increase the stock value.

    The amount by which the stock value must be increased at least can be calculated from the following values:

    1. Transaction MM03, accounting view material master, field 'Total value' (MBEW-SALK3)

    2. Invoice item value according to invoice

    3. In the invoice verification (Transaction MR01, MR1M, MIRO), change the invoice item amount to a value which is high enough and simulate the invoice to receive the value which would be posted for this item to the GR/IR account.

    In the invoice verification, the value (3) minus (2) is posted to stock. It must be larger than (1).Post a subsequent debit with the amount (3) + (1) - (2) for the affected material/plant (Transaction MR22).

    You can post the invoice afterwards.

    (Below one OSS note may also be relevant for you:-
