Hi Urjit,

I got the same error and i resolved by.

Ask your R/3 Administrator to make your username under Public group. Your Administrator can create Public group in R/3 Server then your ping will successful.

Let me know still problem persist.

Dear Suresh,

We have SAP 4.6c .

I told my Basis Admin to make userd id public, but he is saying that there is no "Public" group .

Please clarify.

Problem is solved .

System was not pinging due to logon group in R3.

Logon grp in R3 was null.

I have created logon grp name PUBLIC in R3, which solved this problem.
