Hello All,

We are using EP7.0 and have installed ESS Business Packages successfully but when we goto the ESS role it comes up with an error like :

When I goto Content Administration -> Webdynpro and try to test SLD connection ,it says "Connection to the SLD could not be opened successfully".

It comes back on its own and then I am able to see the Overview Page

Please help. Any help would be highly appreciated.

Thanks for the reply.

The Jco's have been maintained and we already have seen the ESS Overview page and the various services. But sometimes its fine and at other times the SLD service is stopped and we encounter that error. It comes back on its own when we click on ESS tab and at other times its down. I dont know whats going wrong with it .

Please help.

Hello Subhash,

This kind of problem arives when the maximum no. of JCO connections excced. Have a look at the following document. There its mentioned what parametrs you have to set for the JCOs.

Hi Subhash

Looks like you have not maintained the JCo Connection "SAP_R3_SelfServiceGenerics_MetaData' in the SLD.

Log on to the Web Dynpro Content Administrator and Maintain the JCo destination.

On how to maintain JCo:

Please follow the following document to configure ESS:

Cheers.
