Send PO Attachment as FAX

Hi,

SAP has implemented this BADI BBP_DOC_PRINTPROC for converting  external formats to SAP formats and sending FAX.

For this we need XDC (External Document Converter)  . Do we need to buy XDC from SAP or will get it from latest version ?  if NO, how to use that.

when I looked into the  BADI implementation we need to created RFC destinations ( DOCCNV_RFCDEST1, DOCCNV_RFCDEST2,  DOCCNV_RFCDEST3 ) for calling some of  function Modules( RSPO_QUERY_FORMATS) and need to maintain in the table TSPOPTIONS.How to Maintain these.

Anyone worked on XDC ?

Thanks In Advance.
