301 movement type updates moving average price in costing view 2

Dear,

I have got a problem:

Material A had standard price and average moving price(32.1 EUR) in plant 1001, but, in plant 1000, all the prices are 0. (all materials are set price control S)

But, When I used MB1B to post a 301 movement type from plant 1001 to plant 1000, moving average price in costing view 2 and accounting view 1 had been updated with the same standard price 32.1 EUR.

What are factors to influence updating moving average price in cost view 2 and accounting view 1? And How it works from configurations or relations.

thanks,
