Here its my basic question about warehouse and location hierarchy........... I have one central warehouse and multiple stores located in same area.Every store has its own but small warehouse.Stock gets pushed from main warehouse to store level warehouse.So how can i design location hierarchy for above scenario? Secondly i would like to ask is there any approval functionality provided by OpenERP when internal move is created ? Once you create internal move,confirm and validate it,automatically it transfers stock to destination location.I want some kind of human intervention so that this process can be monitored by various users?
