When searching in the timesheet tasks, things like 'Investment Name', 'Investment ID' are not searchable
Release : All supported releases
Component : CLARITY TIME MANAGEMENT
This is working properly. The Search box only searches the '*Name' column.
Instead, a Filter should be used here. Next to the search box, click 'Add Filters' and on the left there will be an Add Filter dropdown where you can add any column, and then create the filter which will display the desired results. As an added benefit, with the filter, you can save the view and also share it.
