Impact of Switching from Standard price to Moving Avewrage Price

Hi Gurus,

I have a scenario that I need to ask.we have selling company codes that only sells to the customer, they don't manufacture.
The selling company codes use standard price costing and now we are planning to move these company codes to use Moving Average price. I am wondering if anyone explains the impact of making the move and what should be the steps involved to safely switch from standard price to moving average price. Thanks

Regards,

Shaiq
