User access permissions to not post

Hello how are you?
I would like to consult what process should be taken into account in the access permissions in order not to post entries by user, bearing in mind that in the Accounting model, it is assigned in the Accounting entry field: permission only to read, but it still allows entries to be posted. Your contributions would be very helpful, this user is an auditor, only visualize but not generate movements. Happy day

If a button has no group, the user just need to have read and write access to the linked model otherwise it must be in one of the group linked to the button. See Access Rights — trytond latest documentation
