Loop for multiple date rows

sunnyal
How do we generate multiple values of a generated single attribute. I was able to generate future date of 4 rows, but what i needed is a 4 rows of different dates as depicted below.
Row No	Date	Usage
1	Jun 15 2017	0.623381
2	Jun 16 2017	0.863356
3	Jun 17 2017	0.564621
4	Jun 18 2017	0.068763

There is a macro in the process called "futuerDates" (misspelled) that is set to 4. When you loop, you set the iteration to "futuerDates" so it does it only 4 times. If you want more, increase that value.

Oops my bad, you said you need different dates. Look at this process
