Planning (MRP): Act on the plan

A planning run hands back suggestions, and this section is about deciding what to do with them. Understand the planned, firm and released states first, because only releasing can't be undone. Then firm or pin the orders you want to keep, carry out the ones you trust, work the Exception Messages inbox, and check what you can promise a customer.
