Using Item availability constraints

When you set up your item database in the MATL table, you can specify whether the availability of a given item will be a constraining factor in the generation of a plan. The MATL.FLAGS field controls item constraints (such as "unconstrained purchased item").

If no item constraints are enabled, the Planner reports the times (or "exceptions") at which projected component inventory is insufficient to support the plan. You can use this exception information to obtain or manufacture the items to meet the projected shortages.
