An RFC receiver adapter, ends in the following error. See below

No SNC was entered or used on Comm Channel, User exists, and is OK.

No idea why tickets SSO ticket is involved, this RFC with no SNC.

What setting to change or how to fix jco pool issue.

Any ideas?

regards

Phil

Thanks for replies guys.

I dont it is password related. I tested this already.

The end system is NW7.1 so no issues with upper/lower case.

I changed the PW to uppercase everywhere just in case.

The Web dynpro JCO info from portal seems to be unrelated.

The only info entered is in an adapter.

The adapter appears in the JCO pool OK, with the correct no of max connections.

I will continue testing and reward points based on outcome.

Thanks for trying to help.

I will also post final outcome when known.

Hi,

check u r RFC in tarnsaction "SM59".......and also check if the host is reachable or not in Transaction "SM49"----


> Pning -


> Additinal Parameters(specify the host name here) ........................

or else

You have to restart the J2EE engine

the steps to do this is mentionaed below:

Transaction code "SMICM" -> administration -> local J2EE instance -> Restart with soft shutdown.

Hope this will solve u r problem.

Reward with points if helpfull.

Hi Phil,

Check these:

1. test RFC destination in Sm59.and remote login from there

http://help.sap.com/saphelp_nw04/helpdata/en/26/64f62cfa8911d386e70000e82011b8/frameset.htm

2. Check you have used capital letters for password field.

hi phil,

This might be password issue, you need to have a password in UpperCase, jCo cannot convert and hence you create a new user with pwd characters in capital case and then try it.

Also check SAP Note 817880

Hi Phil,

May be it is trying to use the Single Sign On feature.

What logon credentials are you using to connect to backend system?

Did you manually try once logging with those credentials?

Also check if the RFC connection is working fine from XI to Backend from XI system sm59.
