Demand Planning in Fulcrum looks at all Items that are set to 'build to stock' or are Make items with 'minimum on hand' set and recommends jobs to be created.
This module should be checked on a regular (weekly) basis so that depleted inventory levels can be replenished before additional demand comes in.
Sub-components (like holster 'Trims' or hardware kits) will not automatically create 'build' jobs from within main jobs that call for those items --- you will need to use a "To Build Override" from within the job to create needed "build to stock" items.
