Layout options in SFC

Options of the Default insertion method for step actions:

Default insertion method option	Description
Copy reference	When you copy the step, the reference to the action objects that are called by the step are also copied. The source step and new step call the same action.
Duplicate implementation	The reference to the action objects that are called by the step are linked to this step. When you copy the step element, new action objects are created for the new step. The implementation is duplicated.
Always ask	When you insert a step action, you are prompted whether the actions of a step element should be duplicated when it is copied, or whether the reference to the existing action should be used. NOTE: If a step already contains an embedded action, new inserted actions of this step are also embedded. Likewise, new inserted actions are not embedded when the step already contains a non-embedded action. In these cases, you are not prompted to select the duplication mode.
