Dear daniel,

Hope you are doing good.

How to switch on jco trace and deactivate it later:

Check note: 628962 - How to switch on the SAP JCo trace

The JCo error "JCO_ERROR_RESOURCE: Invalid connection encountered" means that something is wrong with the configuration of the RFC destination JCORFC. Could you please check the following.

1) Does the user which you defined for the Repository of the destination JCORFC has the authorization as described in note 460089? If this is not the case, please use a user with the according authorization.

2) Is the ABAP system a Unicode system? If this is the case, please select the Unicode flag for the destination in sm59 and in the JCo RFC Provider Service.

3) Increase the connection parameters in the WD content admin screens for the JCo and then check.

Thank you and have a nice day :).
