Instance Method Details

#build_packages(packages = Array.new) ⇒ Object

Build packages as per stock location

It needs to check whether each stock location holds at least one stock item for the order. In case none is found it wouldn't make any sense to build a package because it would be empty. Plus we avoid errors down the stack because it would assume the stock location has stock items for the given order

Returns an array of Package instances
