Getting the above error in SM21 followed by this CPIC one - Communication error, CPIC return code 020, SAP return code 456
Any idea's??
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
