Why do you need multiple value selection when you already have a start and end date? I think you can just use a parameter and set the step size there
Start Date and End Date would just give me all dates. As I said I want a step size of 7 for every date. I am not sure how can this be done with parameters? If yes, would it allow selecting multiple dates at once?
If Financial week commencing for current week is 07-11-16 then when I slide back the date, the next date should be 28-10-16. That means, Start -> 28-10-16 End 07-11-16. (No dates such as 29-11-16 , 30-11-16) should be displayed in slider.
If you select initial value as 07-11-16 in your start date parameter and step size is 7 days then u will automatically get correct dates
Can I have an example please with a sample workbook?
so you want to be able to move the start date (click parameter slider) forward or back and the end date automatically adjusts 7 days forward or back... so always look at 7 days worth of data forward or back with StartDate as the anchor
am i understanding it correctly?
Yes that is correct
