Problem in RFC connection

Hello,

I have scenario R\3 to RFC via xi.

The scenario work ok in dev environment.

I want to add the scenario to test environment and I have a problem with the connection between R\3-test to XI-test.

I checked the connection in SM59 and it's work find.

I checked the connection details and it's looks ok.

When I try to send RFC to from R\3 to XI I received the message:

<b>"lookup of alternativeServiceIdentifier via CPA-cache failed for channel </b>

I need to transfer the scenario to production and is very important to check it in the test system.

Do you have any idea?

Regards
