RAW material price changing without receiving new inventory on PO price

[mani98]

Hi MM Guru,

So we are having a problem that one of our RAW material prices is changing without receiving any new inventory against PO mvt 103 & 105. The user is creating reservations and doing issuance of current stock with 201 mvt but unit price is changing. What can be the possible reason for this? RAW material have a moving average price V indicator. Attaching the image of the report.

This is nature and characteristic of price control V which always calculated as price=total value/total stock

Check 

old price=total old value/total old stock and NEW price=total NEW value/total NEW stock

And also check in case of any subsequent debit memo or  subsequent credit memo for that material and also any goods receipt or goods issue cancelled.
