Error during SAP SNC Logon Test

[Former Member]

I am receiving the following error when performing this test:

Establishing an SNC Connection with SAP we get the following error:

SAP.Connector.RfcCommunicationException: CPIC-CALL: 'CMRCV'

LOCATION CPIC (TCP/IP) on local host

ERROR illegal parameter value (function=SAP_CMTIMEOUT2)/

parameter=conversation_ID / value=49635059)

My ITS-SAP Backend SNC connectivity worked fine previously. We just completed a refresh of the system and recreated the SNC PSE and exported it and the imported into ITS. Everything checks out in STRUST and SSO2 (NONE RFC destination). This problem was posted back in 2/2006, but no one had an answer. Any help is appreciated. Thanks.

- More info - ITS 6.20 PL20 connecting to a R/3 Enterprise 4.72 system.

FYI - we discovered what the error was. You have to make sure the SNC names are the same everywhere in your system (STRUST and ITS configuration). If they don't match, you get an error of this sort.
