Dear Aditya
1) Please explain the below
Why there has to be 3 roles for each of the tabs for each section. IF all the users are going to have 6 section you can have one single role comprising all.
2) Now if you have 2 hierarchies and 20 node in each hierarcy you end up having 40 Analysis components. And if you have one to one mapping for each analsysis componenet you have 40 roles.
Also in some cases for top hierarchies for eg supersales head you can create one more analysis component providing the highlevel hierarhy authorisation.
3) You will have to then assign the roles to the user using these 40 + roles. Donot mix the composite roles (for 6 section) with the authorisation roles. They are independent and has to be provided seperately. You do not end up in creating 500 odd roles for your authorisation
