Wrong IR

Question

Hi all,
Need your expertise in solving an issue. The issue is my end user had received an invoice for particular po( ex-123). Actually for this PO we have already received GR and IR and cleared the payment. Even then the user has posted the IR through invoice verification MRHR without mentioning the quantity. Once the invoice is posted the qty it is displaying as 1.
After this the vendor has noticed the mistake for duplicate invoice he has send and has given the credit memo for the same. During this time, person who is taking the responsibility of Credit memo has given the credit memo . At this time he has mentioned the qyt as 3000 but the value is same as above.
After few month they noitced the moving average price is increased to 5 times because of this . So they have moved this issue to me .
At my end, what I have done is I have reset the cleared item for credit memo and reversed the document. By doing this I have reverse the quantity 3000 and the amount.But I am unable to do the reverse or give credit memo for the invoice( which is showing the quantity 1).
I have tried all the possible way but could not. I need your help in this.
By doing this our aim is to set the moving average price to same as earlier.
Please treat this as very very urgent.
Points will be awarded for the proper reply.

Srini

Hi Sridhar,
Thanku very much for your reply. When I tired through <b>MR8M</b> - I got message " Invoice document no........ does not exit".
But when I tried to cancel the same document through <b>MR08</b>  I got the following message
<b>Moving average price for material 147275 GB01  is negative
     Message no. M8 783
Diagnosis
     This item would create a stock value posting which would result in a
     negative moving average price for the material.
     Note: This message category can be changed in Customizing for Invoice
     Verification. This means that you can receive an error message (type E),
     even though the message is defined in the standard system as a warning
     message (type W). The following documentation only deals with the
     standard case.
System response
     The system does not allow a negative moving average price.
Procedure
Check your entry in the field "Amount" and correct it if necessary.
If your entry is correct, check the following for the material
o  the stock value
   (Environment -> Master data info -> Display material)
o  the posting history
   (Environment -> Line items -> For material).
It might be necessary to cancel past postings (for example, incorrectly
valuated goods receipts or incorrect price changes), before you can carry
out your posting.
If you wish to carry out a price change, the total stock of the material
may be negative. A price cannot be changed if the stock is negative.</b>
Kindly advise me how to proceed.
