Hi,

Check sevral things:

1. Is the JCO Destinations has enough "max connections" - should be set to 200 app.

2. The user using the application is not locked in the backend.

3. Is the mapping to the backend is set on "Ticket", if not check the password on the JCO Destination model data.

4. Is the mapping to the backend is set for user/password for the metadata in the JCO Destinations.

Hi Mathi

Use Try Catch Block

    try {
		model.modelObject().execute();
		---
		---
		---	
		wdContext.nodeOutput().bind(model.modelObject().getOutput());
	} catch (WDDynamicRFCExecuteException e) {
		e.printStackTrace();
	}
