Scenario: I have created a lookup column with two columns. A department column and Expiration Date column. Each Department has a Expiration Date. For example see the image. When the Department Expiration date is met or passed, I want the department to drop off the lookup column list.
Possible Solution:
1. Create the look up column and enter in the department names and expiration dates
I created a calculated column that filters the lookup column and the dates. (I think)
This is the formula I used:
=DATEIF([DepartmentExpDate]=>TODAY,"")
The formula is not working. I am not sure if any of this is correct.
Question: How would I filter the lookup column to have the department drop off the list once the Expiration date equals today's date or passes automatically?
