Hi,

SAP Note 63347 - List: CPIC error codes ---> says that your CPIC return code 2 is related with CM_ALLOCATE_FAILURE_RETRY.

Check that explanation too:

 "Communication error, CPIC return code 002, SAP return code 679" is telling
you that the registration of a communication message (RFC) to a target
system failed.

I may be wrong here, but whenever a new message tries to get through to a
target communication server, the RFC program will re-register itself with
that server. This failure usually happens when there is a large number of
requests in a small time frame e.g. when a batch job sends a load of
messages to a target system. For each request, the system will try to
re-register, but it is already busy re-registering another request so the
attempt fails. This doesn't necessarily mean the communication server is not
available, but it's something you should check regardless.

When this last happened to us, we were receiving hundreds of these CPIC
errors and the only way to resolve the problem was to reboot our the SAP
Business Connector system

Hope this helps,

Arwel.
