we have a Portal Application (WebDynpro) that requires to pick up specific files from an FTP-server through XI (the WD-Application is not allowed to do this directly through the portal framework). The filename is specified at runtime and provided in a parameter. All files are in a directory on the FTP-server, but only the requested one is to be transferred.
We think about sending a request from WD to XI and then have XI pick up the requested file on the remote DTP-server.
a) is this possible with using XI?
b) how can we use/supply a parameter for the filename (value at runtime) in XI (eg. <http://help.sap.com/saphelp_nw04/helpdata/en/0d/00453c91f37151e10000000a11402f/content.htm>)
