Hey there!

I only started working with Sage (we use version 2019 R2) a month ago so please bear with me if the answer is too obvious.

Is there a comprehensive tutorial on what needs to be done when creating a new table so that it works in conjunction with the existing tables? I haven't found any on the "Sage Customer Support and Training" YouTube channel and the one found here is not extensive enough for my limited knowledge on this subject. 

I have created the new table, added fields I deemed necessary, created a view, created a list referencing that view and created a screen again referencing the view.

Problem is: The list does not show up as a system action if I want do add it as a tab in the opportunity tab group. Do I first have to connect the new table to the opportunity table? This probably will have to be done in the database itself and not in Sage right?

Kind regards

Norman
