Navigate to 'Admin' on the menu to the left. In the list enter 'Overview'. 
(Or you can just write ADM in the program line.)


This opens some boxes and the one called 'Settings' is where you will find the Default create values.

Once you enter the Default Create values box, you will have to choose the module/area where you want to define the values, for example 'Supplier'. 
When you enter the 'Supplier' box, a list of values that can be specified are listed. 

Turn on the field and specify the value. 
Next time a supplier is created, this value will automatically be inserted in the relevant field.


You will find the following areas available when specifying default create values:

Product

Customer

Supplier

Sales quotes

Sales orders

Purchase quote requests

Purchase quotes

Service orders

Auction Lots.
