Blocking Bins in the Warehouse 
Occasionally you need to block storage bins. For example, you might want to block the storage bins that are being counted for an annual inventory or bins that have been damaged or are being renovated. When the activity is completed, then you must unblock the storage bins so that they can be used again by the system. You use the same tasks to block and unblock bins.
