In standard the Official Document Number and the Reconciliation Key are not available for selection of an archived invoicing document. It is possible to create a customer archive infostructure with those fields. Just do the following:
- Start transaction SARI and choose the button CUSTOMIZING.
- Create a new customer archive infostructure (possible to copy standard infostructure SAP_FICA_INVDIR).
- Add the missing/optional fields to the tab 'Info structure fields'. 
- Save and activate the customer archive infostructure.
All future archived invoices can be selected and displayed with the customer archive infostructure. In transaction FKKINVDOC_DISP you have to use the button ARCHIVE and choose your own infostructure.
