How do I add an assignee?
Transactions can be assigned to any users who have at least edit access to the transaction screen and any roles that have that level of access and have been assigned to users.
The person either has not been set up as a user or does not have at least edit access to the transaction screen.
Either no users have been set up to use this role or the role does not have at least edit access to the transaction screen.
To add an assignee to the list, you must either add the user with appropriate access rights or edit the access rights of an existing user. If you want to add a role to the list, you must either assign the role to a user or edit the access rights of the role. To set up users and roles, go to Maintain>Users>Set Up Security.
