The Field profile dialog: Validation settings

Confirm

The Verify operator must press Enter for the field in the approve dialog.

Retype

The Verify operator must retype the value of the field after pressing Enter for the field. This is a way for you to confirm that INVOICES' interpretation of the field is correct, and it is useful for fields containing very important data or data that has proven difficult to interpret correctly. How it works:

Confirm and Retype

When both Confirm and Retype are selected, the Verify operator can type a new value, but must type it again to have it accepted.

The result is the same as for Retype if the operator retypes the same value as the already interpreted (and possibly corrected) value.

If the retyped value is not the same as the interpreted (possibly corrected) value, this warning message is displayed: "The retype value does not match. Confirm it." The Verify operator must type the retyped value again and then press Enter.

Must be filled

The field must have a value. The Verify operator must type a value for it if no value is filled in by Interpret. How it works:

Use this setting with care. (What will the Verify operator enter when the field does not exist on the invoice?)

Note: This setting is not allowed for a field if No verification is selected in the Options settings.

Interval – From and To

Specifies a valid range for a numeric field. For example, type 1 and 12 to have Interpret check whether the interpreted value of the current numerical field is greater than or equal to 1 and less than or equal to 12. No decimals are allowed here.

Checksum

Used to perform a modulo 10 check-digit control of a numeric field. See separate topic.

Expression

An expression that Interpret uses when validating the value of one or more numerical fields on an invoice. See separate topic.
