Generate Rows
Generate rows outputs a specified number of rows. By default, the rows are empty; however, they can also contain several static fields. This step is used primarily for testing purposes. It may be useful for generating a fixed number of rows, for example, if you require exactly 12 rows for 12 months.
Sometimes you may use Generate Rows to generate one row that is an initiating point for your transformation.
