problems to execute WI's after client copy

[Michael Marten]

Hi,
after a client copy of production PR4/310 to test IM4/310
I get an error message when I try to execute
a still open WI (created before the client copy in production):
*** An RFC destination could not be specified for the logical system
PR4CL310
 
Any ideas how to change/customize  the setup in test system IM4/310 to
execute such WI's i?
