Updating a list date column

rbutgins21 You can do in multiple ways and easier option using MS Flow or SharePoint Workflow on updates of the list item check if the status equals to resolved then set then set the resolved date column to today's date. Just make sure you set the date once to that use a additional column something like resolved date updated =Yes. This helps you to prevent updating this column any further updates to the column.

Let you have three columns and status is In Progress.

Status         | Resolved Date | Resolved Date Updated

In Progress | EMPTY             | NO

------------------------------------------------------------------

Once the status is changed to resolved

Status         | Resolved Date | Resolved Date Updated

In Progress | Today's Date   | YES

So when you are checking the logic make sure check Resolved Date is empty and Resolved Date Updated==No to make the logic error proof.

Hope this helps.
