Hi,
I have a dataset with a customer, a first year of service and a last year of service. I'm trying to use the Generate Rows tool to build a row for each year of service in the range, but I'm having trouble with the expressions to get what I need.
| Customer | First Year | Last Year |
| A | 2018 | 2019 |
| B | 2015 | 2019 |
| C | 2017 | 2021 |
What I'm trying to get out of this looking for with the output is a row for each year the customer was in service, kind of like an anniversary report:
| Customer | First Year | Last Year | Anniversary Year |
| A | 2018 | 2019 | 2019 |
| B | 2015 | 2019 | 2019 |
| B | 2015 | 2019 | 2018 |
| B | 2015 | 2019 | 2017 |
| B | 2015 | 2019 | 2016 |
| C | 2017 | 2021 | 2021 |
| C | 2017 | 2021 | 2020 |
| C | 2017 | 2021 | 2019 |
| C | 2017 | 2021 | 2018 |
Here's my tool config. Any help or suggestions would be greatly appreciated!

Regards,
Jake
