SQL Update 1 tables columns from a different tables columns

Looking for some help with trying to write a stored procedure that will update 2 columns with values from another tables columns. I have a table that holds inventory items for both wherehouse locations. A user needs to look at what is in Wherehouse A and then builds a list of items that are needed at Wherehouse B. Once the user has done this an order is generated to be filled and shipped out. When wherehouse B recieves the order they check the qty and then updates the transfer request saying whether or not all items were received. My problem now is that I am needing to update the inventory table to show that items from wherehouse A are now in stock in wherehouse B.
I have no problems updating the transfer table when the items are recieved but now I have a problem updating the inventory table to show updated qtys and that the location has changed. What is the best way to do this?

can you describe what sort of tables and fields you have, and what sort of procedure you are after? i.e.

inventory: location, stockcode, current_qty
sp: input - locationfrom, locationto, stockcode, qty

something like

create procedure stockmoved (  @locationfrom int, @locationto int, @stockcode int, @qty int )
as
update inventory set qty = qty - @qty where locationid = @locationfrom and stockcode = @stockcode
update inventory set qty = qty + @qty where locationid = @locationto and stockcode = @stockcode
