Net Change or Regeneration

Select Net Change to allow MRP Planning to plan only for those items (or item-related records such as jobs that produce the item) for which the Net Change field has been selected on the Items form. You can select this field manually for an item, but the field is also selected automatically when the item has undergone some activity that changes MRP requirements information. For example, actions such as performing a Miscellaneous Receipt for an item, changing an item's Low-Level Code or changing lead time values would cause the system to select that item's Net Change field automatically.

Select Regeneration to delete the existing MRP plan records and regenerate the entire plan for all items using the latest requirements information. This option may take a significant amount of time to complete if you perform it on a large database.

Always run the Current Bill of Material Processor and the Job and PS Bill of Material Processor before running a Regeneration. This step ensures that the low-level codes for all items are accurate, which is critical when running a Regeneration.
