To define a routing operation you first specify an operation sequence number to indicate the order to perform operations. Components in your bill of material can reference an operation sequence. Next, you can choose either a standard operation, or you can enter a new operation.

1. Sequence of Operations
Routings define the step-by-step descriptions, or operations, for manufacturing an assembly. Each operation on a routing defines a specific portion of the manufacturing process for the assembly. You can use operations to identify the location, the quantity, and the state of completion of the assemblies you are currently manufacturing.

For each component item on the bill of material associated with a routing, you can specify the operation sequence where you require the item. You can then only issue material where and when it is needed.

2. Code (Standard Operation)
A standard operation is a commonly used operation that you define as a template to default operation information when you define routings. When you define a new operation on a routing, you can specify a standard operation whose information Bills of Material copies into the operation you are currently defining. You can then change any of the copied information for the new operation.

Setup Standard Operation
A setup standard operation is the same as a standard operation except that it defines an operation used for setting up machine type resources only. Use the setup standard operation to specify the operation used during changeovers.

3. Enter the department in which the operation is performed.
If you have entered a code then the depart would default from the operation code

4. For operations in ATO model or option class routings only, indicate whether the operation is option dependant, that is, whether the operation is dependant on the choice of an optional component. All mandatory components and their related
operations appear on the routing for each configuration. The default is enabled.

5. Optionally, enter the item's manufacturing lead time percent required to complete all previous operations on the routing.
If the manufacturing lead time equals 10 days and all previous operations combined require 2 days, the lead time percent is 20%.
