Dear All

I wanted to ask how we can create a dummy age and date of appointment for 170 people for 20 years (a total of 3300 new cases) . I have 379 people in my dataset and I wanted to know if there is an easier way to create 3300 dummy cases with age assigned as the following for each year starting from 2021 till 2040.

First 5 cases assign age as 22
>5-20 -23
21-50 - 24
51-100-25
101-120- 26
121-135-27
136-140-28

The appointment year should be filled up simultaneously as 2021 for the first 165 cases and then appointment date as 1-1-2021 for the first 165 and then 1-1-2022 for the next and so on till 2040

Please find below a sample or my data set. These are the 739 cases and now I need help to generate the remaining 3300 cases with the above condition.
