Hello Experts ,

RFC from CRM --> ERP is failing when i enable SNC , error is indicated below :

"Connection closed(no data)" -

After exchangin the certifcates i get different erro :

"When executing a remote function call , an error occured"

I checked the dev_rfc but no information.

Steps i carried are as followed :

  1. SNC name of ERP in CRM RFC.
  2. SNC name of CRM in ERP in SNC0 (Tx).

Please let me know if i missing something.

Thanks
Dev

Hi,

maybe missing authorization. Try to run authorization trace (ST01) to see if you user is missing any authorizations. ST01 also has RFC calls trace. I would try that one as well.

No luck Martin.

Hi,

where did you perform trace? Caller or callee? I would also check ST22 in both systems for dumps. Also check SM21. Honestly, it's really hard to guess what is your problem. So I would check all possible logs.

Was it working beforehand?

There was a bug about 12 months ago which prevented SNC for server-to-server RFC. What is your kernel version and patch level?

RFC works fine without SNC -both the systems are having kernel release 740 and patch 14.

Then something is wrong in the config of the SNC or RFC attributes.

But there is not enough information here to say what it is.
