Dynamic date range creation for WebI query
I have a webi query where I need to provide a date range as selection. But the from date will be based on number of days that user will provide during query execution. For e.g. user will give no of days as 10 so the date range need to be created as (system date -10) to (system date).
I am not sure how to provide the option for user to input no of days and then calculate the date range.
Could you please help me here.
