RFC call failed while configure SSO between NW7.4 and ECC EPH6
I have a porblem while run t-code RZ70 (Gateway Host: portal_host name, Gateway Service: sapgw00)
"RFC data prepared
Used RFC destination: SLD_UC
RFC call failed: Error when opening an RFC connection (CPIC-CALL: 'ThSAPOCMINIT' : cmRc=2 thRc=67
I have done these steps:
1) Set SSO parameters in the backend ABAP system ECC EHP6 by the t-code RZ11
2) Add CA of EP into backend.
3) Create a "system" in EP and finished OK.
but show " Connection failed. Make sure user mapping is set correctly and all connection properties are correct. " while testing.
4) SLD Configuration
So, Can anyone tell me where the problem is taking place?
Thanks & Best Regards
