Upload receipts to IXOS server

Hi,

We are trying to provide an attach receipts functionality on the SAP eTravel portal.

The standard functionality stores the document using Generic Object services (CL_FITV_GOS=>SAVE).

We need to upload the document to an IXOS archive server.

Is there any approach that we can take where we could use the standard functionality provided by SAP but redirect these files to be loaded on the IXOS Archive server?

Regards,

Rufus.
