Invoice modulesWhen is selected on a single item field, the field value found in the learning invoice (or in the invoice definition learned in the Invoice Optimize module) is saved in the invoice definition. All invoices associated with this invoice definition will have this value assigned to that field.
This makes the value for that field static, though it can be changed in the Invoice Verify module.
You use this setting when:
A field value is always the same for a particular supplier
You need a field value that does not appear on the invoice
Currency fields and bank account fields contain this setting by default.
Example
If one of your suppliers always has the same tax rate, you can select for the tax field. This ensures that the same value is always used for the tax field, and it improves extraction on invoices from that supplier.
The system still searches for the field in the position where it was learned.
If the field is found, the field status is green/Complete.
If the field is not found, the field status is yellow.
Regardless of whether the field was found or not, the value is always set to the static value specified in the invoice definition.
By using the setting in combination with , the field will always be set to Complete in Invoice Verify, regardless of whether it was found or not, or whether it has validation errors. See Setting Supplier fields to Complete automatically.
