Getting value repeated for next year if value is recurring - sql

Question

I have a record for project and release number and I need to repeat the row in next year if value is recurring.
First image is showing the data that I have it
My expected output is:
Explanation of output: In year 2017 value_type ITA has frequency as Recurring so, This value should be repeated in all next year(i.e 2018, 2019 and 2020). like that in year 2018 OC and PA is recurring so it also need to repeated in 2019 and 2020.
For that I created a new view for only recurring value and tried to join that view with base table. But it is not giving me proper result.
Can anyone please help me with this?
Thanks in advance..

DECLARE #EndYear INT =2020 --Also you can get from data by MAX(Year)
