Specify number allocation for field
Go to Settings and maintenance and select Options.
Select the Number allocation tab.
Double-click the required counter in the table. A dialog for the selected counter opens.
Check Unique if you want the counter values in the Number. field to be unique. Useful when SuperOffice CRM users allocate values themselves.
Check Allow blank to permit empty counter fields. Useful when the counter values must be unique. If Allow blank is checked, this means that the requirement for unique values does not apply to empty fields.
Check Read only if you do not want SuperOffice CRM users to type values into the Number field themselves.
Check Allocate to use the automatic counter function, so that the system enters values in the Number field for you.
The Next number field displays the next number to be used. You can change this value if required.
