If you are using the T7SOA (GUI version) you can click on the Notepad icon to enter a note. If your default setting for "Enable Evo Notes System" is set to N then the only Note type that you will be able to print is CSN. If you set the Use Evo Notes System to Y then you can control the printing of different Note types on different forms.
