I am using the webMethods SAP Business Connector Server verion 4.8. We have a very basic setup. We have an RFC call from SAP to the BC server that passes a SQL statement. The BC Server connects to an Oracle database and returns an Updatecount (for insert statements) or a Rowcount and results table for select statements. I used the standard delivered service execSQL to connect to the database. I am using the JDBC OCI driver provided by Oracle.
The problem is that if the DB passes an error back to the BC server, then the BC server does not forward that error on to SAP. Instead, SAP just gets a SYSTEM_FAILURE error with no details. It doesn’t matter what error.
For example: If I pass an insert statement and don’t provide a key field in the table, then Oracle passes an error message back to the BC Server. From SAP I just get a SYSTEM_FAILURE message with no details. From the BC Developer I get a popup window with a detailed error message from the Database. The service does not return anything.
It seems like the service shoule pass the database error back in the $dbMessage field. Instead, the service fails and exits the flow. Since the flow is lost there is no link back to SAP and SAP receives the SYSTEM_FAILURE message.
I have no custom code in the flow. Only the standard delivered service “execSQL” and a map to map the execSQL service to the RFC.
Does anybody have a suggestion on how to capture this error message without exiting the flow?
