Moving Average Price

Dear Expert,

We are using Moving Average Pricing for Inventory Valuation. We have a concern as follows:

I issue Material-A Qty 10 @ 100 using 281 Movement Type.

After few months I return these Materials back to the inventory as Return Delivery or as Cancellation using 282 Movement Type.

Since there has been other Procurements for Material-A, Moving Average Price has got changed and it has return at 10 @ 105.

Is this is a standard behavior when using Moving Average Pricing? Is there is away to stop this (Return Goods at the same value)?

Appreciate your guidance,

Dileepa.
