How to pass XML(Binary) to Server Proxy in ABAP report

Hi,

I would like to schedule server proxy in back ground mode using ABAP report. I already have the payload available in XSTRING(binary) saved in Z table. I know how to convert binary string to XML (using FMs -  SCMS_BINARY_TO_STRING).

However, is there any way to pass binaryXML(XSTRING) to server proxy (without converting the paylolad to XML and use SAX/DOM parser to populate proxy input structure ) ?

Not sure, if SET_XML(IF_WS_PAYLOAD) method can be used.

Thank you,

Mallik
