You can disposition SFC numbers from a Production routing to either a Special or NC routing. You can also disposition SFC numbers from a Special or NC routing to another Special or NC routing. In other words, you can create several layers of Special and NC routings.

To return SFC numbers to the step they came from, you can use return steps on your Special and NC routings. When you use return steps with these routings, the step returns the SFC number to the Production or NC routing it last came from. All return steps skip special routings.

For example, you may allow operators to send SFC numbers to an NC routing from a step on a Production routing. Then you may want to allow operators on the NC routing to send SFC numbers to another NC routing. If you use a Return to Original step on your NC routings, the system returns SFC numbers to the NC or Production routing they came from. The following graphic depicts this process:

As another example, you may allow operators to send SFC numbers to a Special routing from a step on a Production routing. Then you may want to allow operators on the Special routing to send SFC numbers to another Special routing. If you use a Return to Original step on your Special routings, the system returns SFC numbers to the NC or Production routing they came from, but skips any special routings along the path.
