I use sharepoint 2010. I created a field called REMAINING DAYS, to compare it with the DATE OF EXPIRATION field with TODAY'S DATE.
I used this tip: Tip
The problem is that the calculation is not dynamic. To update the count of the REMAINING DAYS field I have to update all the items in the list so that the calculation is redone.
1) How can I have the REMAINING DAYS being calculated automatically daily?
3) Or with each entry in the list page, the recalculation was done with the update of the flag column (1 or 0).
4) Or via Workflows? Or Powershell?
