Can you help with user setting

Hi

I need to restrict access to modules to some users for instance I don’t want some user to create, edit or delete opportunities just to view them, I created roles, group but this doesn’t work can you help?

the create rule comes with the upgraded package - https://store.suitecrm.com/addons/securitysuite

Will need screenshots of how you have set this up

Opp module - Enabled -

All rules set to = NONE

Except
list = All
view = all

Remember to
Add the user to the role
Add the Security group to the role
Add the user to the Security Group
