In addition to assigning lot numbers in Shop Order Entry/Maintenance (SFC500) after the shop orders have been released, users can now pre-assign lot numbers during the Multi-level Shop Order Release process (SFC530) and the Multi-Level Backflush process (LMP600) for sub-assemblies that are lot controlled items. The user has the choice of using the parent lot ID, the next sequential generated lot ID, or not pre-assigning lot IDs. Multiple items per lot must be installed to use the parent lot number option.
