Hi Swathi,

Your log is clearly saying that issue with JCO.

1) Check the JCO's are pointing in to the correct R/3 system which you required.

2) Check the JCO's status also

And also double check RFC at the back end RFC enabled or not?

While creating the Model make sure that backend server name , client , system number ...etc all are giving correct where the RFC exists.

If all above points "yes" why dont you try with J2EE complete engine restart. Still issues get back to me.

Hi All,

Thanks for your reply. That was the problem from my side. Instead of giving en in language tab i was giving ENG .

Hi

try to ping and test your JCO working or not .....

if yes then Check whether you are providing the correct login credentials while importing the RFC.

Thanks

Hii,

ur exception shows that u have problem with the JCO connection only.Check out ur jco's.

U can restart ur j2ee engine and then start recreating the model . Also check out at the R3 side whether the RFC is working properly or not.
