Hi,

The error message "Could not create JCOClientConnection for logical System" is only triggered when the WebDynpro application is requesting more JCO connections than the number of JCOs allocated for this application.

I suggest to carefully go through the documents below in order to properly configure your JCOs. If necessary, remove them and recreate in the correct way:

JCo Quick Summary

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/85a483cb-0d01-0010-2990-c51...

How to Configure the JCo Destination Settings

https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/3103eb90-0201-0010-71af-be6...

You will have to calculate the maximum number of JCo connections to each application based on Models and users.

Br,

Javier
