I want to add one tab named "Associated Actions Items" into the Lessons Learned Properties Page.Is there somebody showing me how to do that? Thank you!
Don't think we can add custom tabs to custom objects/sub-objects.
( project is "special" because the portlet page is configurable )
My purpose is just that when you open one lessons learned belonging to one project, then you can see the "Associated Action Items" Tab then you can go to create one action associated this lessons learned like to make one technical note...etc.
I would be careful of trying to "design functionality" that just doesn't work in the product. You are working with a COTS product here not a development environment - you are limited to what configuration you can do with the product so you must understand what that is limited to before you start to offer your users some imaginative functionality.
Guesses; (since I don't know much about your "lessons learned" object)
