Hello there,

We have recently build a system form systemcopy of other system.The SAPOSS rfc connection of this newly crreated system is not working.

This is aix 7.1 box wih oracle 11g database, SAP release erp6.0,EHP6

From SAP OS we are successfully able to connect to saprouter on port 3299. In saproutertab file we have done the entry for SAP system also with required permission. But still we are not able to connect to SAP.

Checked with network team and they confirm that they have opned bi-directional traffic from SAP router to sap system.

Below is the error we find in dev_rfc trace file -
