</MappingTrace>

However i've tested with same input message in Operation Mapping ESR, without any error.

What could be the cause?

Thanks, in advance.

Hi,

Are you using parameterized mapping or RFC lookup in your mapping???? If yes, please make sure that you are passing the parameter in the interface determination instead of null value.

Also verify whether your cache is updated with the latest GUID of your mapping program or not.

Regards,

Priyanka.

You are right... there is a RFC lookup and parameter is not set correctly... Thanks!

Hello,

Please check that your variable guid .its coming empty or check other variables which has been madetory but you are not sending any value or sending wrong value.

Thanks
