Begin Step

The begin step is where all charts start, and cannot be removed, cut, or copied. The begin step is where you can define initial values for your chart's scope. These initial values are also hints as to what parameters your chart expects. If the chart receives any of these parameters as starting parameters, the initial values will be ignored.

One of the chart parameters defined on the begin step may be marked as the "Key Param". This means that this parameter may be used as an identifier for the chart. For example, suppose your chart defined the automation process for a car through an assembly line. You might define the car's VIN as the key param. This means that instances of this chart may be identified by the VIN they were started with.
