Upload receipts to IXOS server

Hi,

We are trying to provide 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 could take where we could use the standard SAP functionality and redirect files to IXOS server.

Regards,

Rufus.
