This table contains all the default values for actions based on the system Web Part Request INSERTHEAD. The system Web Part Request INSERTHEAD will give you the basic values, but you can define an extra criterion by setting a default value. For example, if you want the action to create a new sales quote in the Sales Header table, you need to enter 1 in the Field No. field for Document Type and enter 1 in the Default Value field for sales quote.
The rest of the field in the EP WPR Header Create Criterion table is filled in automatically by the program when you define the criterion.
