Cancel returns and Cancel order movement types

Hi,Gurus,

I customized 2 movement types for a client,and so far they worked perfectly.

Now the client reevaluated his requirements an wants some changes on the 2 movement types characteristics:

-for 901-Cancel returns-currently the stock comes back in restricted stock(R-returns)-needs now to come back in unrestricted status

-for 951-Cancel Order-currently the stocks are deducted from unrestricted stock-it needs to be deducted from restricted(R-returns) stock.

Any help in adjusting these 2 movements types will be greatly appreciated.

TY
