R/3 - (RFC) - XI - (File) - Legacy System

Question

Hello there,
  I followed a document to setup SAP XI to/from external systems.
  I did a setup that execute bapi QIRF_SEND_CATALOG_DATA from R/3.  Then, it uses RFC to transfer data to XI, and store as a file @ Legacy system.
  When I executed the BAPI with the RFC destination as created on R3, it failed.
  Besides, when I check the message monitoring at XI Runtime Benchmark, it shows an error as :
     ErrorCode:ICF-NF-http-...  HTTP 403 Forbidden.
  I believe I activated ICF engine service.
  My question is "do I have setup Single Sign-on" for XI or is that optional?
  I followed the instruction call "How to Configure SAP XI to use the standard SAP communication APIs (idoc, bapi, rfc) from external systems".
  Any comment is appreciated.
  Thank you very much.

  Again, I follows an scenario to execute an bapi at R3 using RFC to IS, then put as a file at Legacy system.
  On R3, I did some setups:
    - created an RFC type TCP/IP with gateway hostname and id pointing to R3, and a reg Prog ID named CC_RFC2XI.
    - call Trans: SXMB_ADM to setup Intg. Eng. Config with the role as Appl System & Intg Server point to http://<host>:<port>/sap/xi/engine?type=entry
  On the Intg Dir:
    - created comm. channel from R3 as SAP_2_EXT_RFC as sender with the hostname as R3 host and gateways, and also Prog ID named CC_RFC2XI.
    - created comm. channel for Legacy system as SAP_2_EXT_FILE to stored file as .txt file at legacy system.
    - created Reciever Determination with condition as BAPI execution condition
    - created Interface Determination for interbound interface.
    - created Sender Agreement.
    - created Receiver Agreement.
  - I activated /sap/xi/engine from Trans SICF and also insert user login and password.
  I tested the connection for SM59 from R3 and it's ok.  However, after execute the BAPI with the destination RFC as created, I got the error message above.
  Please tell me what else I am supposed to do.
  Again, I really thank you so much for all your time and help.
