Reciever Determination error

Hi,

My scenarion is File->XI->FILE based communication.

I am using the SAP XI3.0 SP12. I am testing the configuration in the Integration Directory(ID) using the "Test Configuration" functionality in 'Tools' menu of ID.I am getting an error at step 2: Received Determination. Here is the error I see:

Internal Error java.io.IOException

Your changelist is not empty. Activate changes before simulation

I have seen on sdn that for this we should check url of the Adapter engine on our XI Server.From where and how we can check the url of adapter engine on xi server.

If there is some other reason for this problem plz help me out for that.

I would appreciate your comments and suggested remedies for the error situation.

Thanks,

Rekha
