Updation of Moving Average Price

Question

Dear Experts,
My MM period is open for 2 months (i.e for July and August Now) . One of our raw material is Limestone.
From July 1st there were several Receipts and Issues of limestone in SAP.
In August 9th our survey team found that in our stock we have 25000 TON limestone excess. (Due to Callibiration error)
i.e If the current stock in system was 10000  TON the real Physical stock in storage was 10000 + 25000 TON.
We have created a Free of Cost PO for 25000 TON to account the excess quantity of Limestone in Stock.
MIGO Goods Receipt for the Free of Cost PO was done on 31.07.2011.
Because of the extra 25000 TON Free of Cost Limestone Receipt the Moving Average Price of the Material got Updated. (But only from 09-August-2011 not from 31-July-2011)
I want system to calculate the new moving average price and update all the documents posted from 31-July-2011. MY MM period is not closed.
Is it possible to do so and how. Please Help.
Thanks

Hi
The physical inventory is carried out on the basis of stock management units.A stock management unit is a non-divisible part of a stock of materials for which a seperate book inventory exists.A stock management unit is uniquely defined by
Material
Plant,storage location
Stock type
Batch
Special Stock
Each stock management unit of a material is counted seperately,and the inventory diffreneces are posted per stock management unit.
The physical inventory process comprises three phases
1)Creation of physical inventory documents(MI01)
2)Entry of Count(MI04)
3)Posting the difference(MI07)
1)In the first phase ,you create the physical inventory documents.SAP systems provide several procedures for mass-generation of PI documents.After selecting the stocks to be counted and creating the PI documents,you print out the documents in order to start the counting process.A physical inventory document cotains data that include
>The plant and storage location in which the count has to take place
>The date on which the count has to take place
>The materials to be counted
>the stock types to be counted
>The status of the item
>The status of the PI document
When creating a PI document,you can specify a physical inventory nuber in the document header.This physical inventory number facilitates selection of the PI documents to be processed during entry of the count data,posting the diffrences, and in evaluations.
2)Entering the physical inventory count:For the physical inventory count,you must print out the PI document and forward it to persons responsible for the count.You can enter the stock figures in the system with and without reference to a PI document.When entering the physical inventory count,you can enter a percentage variance of the count quantity from the book inventory,above which the system issues a warning message.
3)You can post the inventory diffrences either via list of differences or via seperate transactions.When an inventory difference is posted,the system creates a material document and corrects the stock figures,and an accounting document recording the necessary accounting movements.
Hope this will be helpful for you.
