RFC_ERROR_COMMUNICATION

Hi,

I have installed a EP6 SP9 with WAS6.40 SP9 and I am trying to create a RFC Destination in the Visual Administrator. I kept getting the following error when I start to run the RFC Destination. The error is as shown :

Hello Mike

add the line:

sapgw00 3300/tcp # SAP System Gateway Port

To the File C:\WINDOWS\system32\drivers\etc\services.

Hi Gregor,

Thanks for the hint, I was having that same problem, and your fix worked. Can you share where you found that fix from? Was it an SAP note or something?

Thanks,

Hi Gregor,

I have this same problem in XI calling the R/3 server using a RFC adapter. I have added the line about the gateway and port onto C:\WINDOWS\system32\drivers\etc\services in the R/3 box. Should the system be re-started for it to take effect ?

Regards,

Ashok.

Hi everyone, i have the same problem, but with a different context, i can't have access from BEx Query Designer but i can work perfectly from Workbench. When i try to enter to the Q Designer, shows the message error:

SAP_CMINIT3 : rc=20 > Connect to SAP gateway failed

Do you know why the GWHOST is 140.50.8.243? (Because the IP server is different, & i don´t know when i logg in in Q Designer send this message)
