Previewing data in load scripts
You can preview the results of your load script without fully running the load script. When you preview data, you limit the rows of data loaded for each table and ignore any Store statements in your load script.
By default, 100 rows for each table are loaded during preview. Store statements in your load script are skipped. You can change settings by clicking 
in Preview data and changing the preview settings.
You can view previewed data and profiling information by clicking the Preview button.
