The Drill Down feature in Order Time is used to create work orders for components in a work order that are also bill of materials. This Bill of Materials structure is called an 'Indented BOM'. Consider the example of a computer which is comprised of several 'sub-assemblies' like Mother Board. Each one of the sub-assemblies need to be built before the final assembly (the computer can be completed). The Drill Down feature makes it easy to create work orders for your sub-assemblies.
