In NetSuite, custom roles provide you with the flexibility to create and adjust roles according to your specific preferences and permissions. With this, permissions are provided by NetSuite and determine what data and interface users have access to. Permissions are tied to roles, which are assigned to users. Depending on the role(s) a user is assigned to, they’ll have access to certain permissions tied to their role(s).
Scenario:
The custom role has a Full access to the Track Message permission, however, the capability to delete messages is not available.
Solution:
In addition to having the Track Message permission, it is necessary to have Full access to the specific record, such as a Sales Order, in order for the Remove link to be accessible.
