JDBC-RFC no errors at XI BOX still records were not update at Target system

Question

hi
am doing jdbc to rfc scenario
tested rfc at target  R/3 and its working fine,but records were not being updated in jdbc-rfc scenario.
i can see the audit log as success but no record is inserted at the target system
think problem is at FM.
please look at my FM code.
