Material Valuation

Hi All....

We have the following Scenario in our implementation..

We recv the Goods from the Vendor for Material-A at Rs. 20/Unit, then we make the GR with External batch input (batch-1)

We then recv the same Material-A on other date at Rs. 25/Unit, then we GR with External batch input (batch-2)

Our client requirement is, while doing Issue to Production any batch should be selectable (this is by default ok)

My question is, if we set Mvng Avg Price valuation for this material, and managing with batches, *will the unit prices are seperately picked up while issuing or different batches are averaged? means in this case avg price of both batches is Rs. 22.5/unit

But the requirement is, while costing seperate prices should be pulled....means when Batch-2 is issued, system should take 25/unit only...

Pls guide me as I'm confused with this scenario, someone suggested Material Ledger be maintained...

Kindly suggest how to configure this requirement....

Thanks in advance
