Incremental refresh setup for the future year

Hi! anusha_2023 

Your end-date parameter will decide the refresh parameter for our case. And you should use days in your incremental refresh period or when your data changes. There is no point to use 2 years, else you'll not utilizing your complete data, it's refreshing your complete 2 yrs data.
Please go through this doc for better understanding, ou can change that time period and your Range end parameter will ensure your refresh is being done until the last day.
