Use the amount type for fields on the invoice that contain a monetary amount.
INVOICES handles amount fields in a special way when interpreting them and capturing the field value.
A predefined field format and format specification are used. That is why and are disabled in the settings of the field profile when you select as your format type.
INVOICES interprets the value in an amount field correctly even when the value is written in different ways, like this:
100.00
100,00
100:-
100;--
100
INVOICES displays amount fields in Optimize and Verify, and transfers the field value, in a standard way regardless of how the value is written on the invoice. Values where the decimal 00 is missing on the invoice have 00 added. The thousands separator and decimal separator are standardized. This is controlled by settings in the [Interpret] sections of Eiglobal.ini and Eiglobalextra.ini.
Amount fields can have any number of decimal places between 0 and 7. INVOICES displays the actual number of decimal places in Verify and Optimize. You can specify the number of decimal places for a field in Optimize. The number of decimal places to transfer for an amount field is set to 2 by default, but you can change this in the transaction description.
Choosing the field format type: Regular, date, or amount
