To block item to get issued or receipt, this done by 2 ways: 1. Via Quality Orders and 2. Manually block.
Note: Item which is having stock as on hand can only be blocked
However the problem here is that each separate line must be created separately for each item to block, not in bulk like the Journals and unblock requires simply deleting this line. Also note this is usually items as part of Quality procedure do not use this form like blocking item as complete in general.
