The File Input for Customer Invoices does not use the standard webservice Managecustomerinvoicerequestin. 

In order to add the extension field to the webservice used in the File Input for Customer Invoices, you need to extend the extension field to be used from:
- <BusinessObject> -> CustomerInvoiceRequest. 

For example, you need to enable the extension scenario: Sales Order - General Information to Invoice Requests - General Information. If you enable this extension scenario, the extension fields will be automatically added to the correct webservice used in the File Input.
