Hi,

The return code 456 indicates that the connection timed out during

setup. To rectify this you need to first verify that the destination and

the called FM are available. can you please verify that

destination exists and check in transaction SM59 whether it can be

tested successfully. Also ensure that the called function module is

available ->

What is happening is that the connection setup is exceeding the maximum

wait time specified with the gw/cpic_timeout parameter in transaction

RZ11. Once you have verifed that the called destination and function

module are available then the only other thing that could be causing

this problem is poor network performance (just taking too long to

complete the connection setup). If this is the case then you need to

increase the gw/cpic_timeout parameter in RZ11 to allow more time for

the connection setup to complete.

Regards,

Sumanth

Thank you for your response. We have some network issues that are causing comms errors. As soon as they are sorted out things should go back to normal. For the time being I have cancelled the connection causing the problem and deleted the entries in the gateway monitor.
