[Former Member]

Hello Everyone,

Our B2B system is connecting to SAP. in between 900 to 1100 seconds connection is being closed after a cancel request issued by the SAP system.

with a RFC return code:

Return code: RFC_CANCELED(20)

error group: 112

I have checked below link which has the list of RFC return codes. Please advise me to resolve this issue.

Could be JCo connector issue. What is your JCo version ? probably get latest version of the JCo connector.

Try to see if note 1467969 helpful.
