Lookup list with entries from calendar only for the past two weeks

Question

we have a calendar where we enter when and which trainings will take place. Now I would like to use a lookup column in another list and get the title of those trainings (which is no biggie) but we need the trainings only for the last two weeks. Can someone suggest me a way to do this? I've tried with workflows in SharePoint designer but it didn't work.

Answer 1

In the parent list of the lookup column, you can create a new calculated column, which uses a formula like =IF(([AssignDate]-Today())<14, Title,""). Then this column will have value only if the column AssignDate has a value for the last two weeks. Then change the look up column to get value from the calculated column. It shall work now.
