I created an application using Sharepoint list for legal case management. Now I would like to add an option by a user to perform an action (travel, presence in court, drafting, etc) regarding a case (day, time and other 2-3 information about the action itself). A case can have 10, maximum 15 such records. I thought of creating a new list with the necessary columns and taking items such as case name, with lookup from main list. The problem is that I don't know how to make the connection in the main list when I want to see the details, to be able to acces the afferent records from the "transaction" list.
