Ok.
You have to use two “Date time to string” node respectively with yyyy and MM pattern
After you can compute financial year with a simple math formula or a Java snippet node that tests if month is greater than boundary value and build output string.
Thanks for your effort, but in second row I am getting Financial Year as 2019-2019, it should be 2019-2020…
See because,
Financial start from April and ends in March next year.
for example: 01-April-2019 to 31-March-2020 and your date 31-12-2019 will fall here, i.e. 2019-20.
