Exploding Repetitive Schedules
Once you establish a schedule, you must explode it using Schedule Explosion (18.22.2.4). The explosion creates the material and work center operation requirements necessary to support the schedule.
Until exploded, changes to the schedule are not reflected in component demand or work center load. MRP reports for the components or CRP reports for the affected work centers do not reflect the current repetitive schedule until it is exploded.
The schedule explodes automatically when MRP plans the item and site or when you run Schedule Explosion. An exploded schedule creates scheduled work orders for each day of production. Review these work orders in the Work Orders module. They have a type of S (scheduled).
Run Repetitive Picklist Calculation (18.22.3.1) to see if shortages at work centers need to be corrected.
