the all over description is that

i have already create location on duplicating the stock from go to configuration ->location

location name are : chiran,chemical,season,finish.

i have create a three sub menus in internal moves (warehouse) as :

1> chemical wood entry

2>seasoning wood entry

3>finish wood entry

so i want that when i go to chemical wood entry and click on Add item: where i have shown field source location as:

(Physical location/Your Company/stock) i want to change it as : (Physical location/Your Company/chiran)

and desination will be: (Physical location/Your Company/chemical)
