Hi Experts,

Hi Mehul

Kindly check the JCo that you have used(Do both Ping and Test). This error appears when the application could not get connected to the R/3 System. Also check whether the SLD and R/3 System are running(i.e both the servers need to be up).

Let me know the result.

Hi Sivaprasath,

Thanks for reply. I did both ping and test. On testing I am getting above pasted error and

on pingin it says Jco pingin failed.

SLD and R/3 system are running fine.

Moreover, I am able to create model on NWDS using adaptive rfc using Jco created. but on executing, getting the same error as result.

Is there any specific roles need to be assigned with BackEng user login we use for Jco?

Hi Mehul,

I think you need to check if you have the appropriate entries in the /etc/services file on your application server:

For example something like this (change port number to the appropriate value):

sapmsDV2 3609/tcp # SAP System Message Port

Then it should work (I hope, because I had similar problem a year ago).
