You can step a component multiple times during a simulation, to preview the behavior of a component with different property settings. Repetitive stepping does not increase the number of records delivered to the downstream component.
Stepping through components multiple times
In the Design window, click the component.
In the Properties window, modify the transformation rules or property settings.
Right-click the component and select Initialize.
Right-click the component and select Step.
Return to step 2.
When stepping a component repetitively, the same set of records at the IN-port are reprocessed in each step and forwarded without increasing the number of the records at the OUT-port. You can step through many components from inside the component window, or by using the menu that appears when you right-click in the Sybase ETL Development window.
