JDBC Mapping problem

Hi,

We have designed a JDBC to R3 scenario.

Data is picked up from Oracle database and updated into Ztable in R3 system.

Here data from the Oracle database can have multiple records.

I am done with the Integration Design and configuration.

When I run the scenario, I got a Success message in SXMB_MONI on the outbound and inbound.

But data is not getting mapped.(I am not getting any error in the Mapping area).

I tried testing the message mapping with the actual payload from the oracle system.

I am not getting any error but data is not getting passed to the target data elements.

What can be problem. Can anyone guide me on this with suitable examples.

Thanks

Kumar
