Modifying components
To initialize a component, right-click it and select Initialize or select Initialize
and Step from the pop-up menu.
If you modify one of the existing property settings of a component during
simulation re-initialize the component prior to applying the next step.
Data blocks and visualization
When working in simulation mode, the entire result set of the data source (as
defined by a query in the source or staging component) can be divided into data
blocks. A data block contains a subset of records. The number of records in
each subset is related to the Read Block Size parameter in the Property section
of the component. Choose a small number for the Read Block Size parameter
to enhance the performance while stepping through the project.
❖ To preview the result of a transformation
1 Step through the project including the component you want to preview.
2 Right-click the component, port, or the connecting Link.
3 Select the Preview command. If a component has multiple ports, select the
port from the drop-down list.
Stepping a component multiple times
