Issue in ABAP Proxy

Hi Folks,

I'm having a strange problem, I'm currently working on a proxy to file scenario. If I'm directly testing the proxy i.e. executing the proxy class directly I'm receiving the file proper in the file system. But when I'm executing the proxy grom (ABAP Program) I'm getting an error saying

<SAP:P2>com.sap.aii.utilxi.misc.api.BaseRuntimeException</SAP:P2>

<SAP:P3>RuntimeException in Message-Mapping transformatio~</SAP:P3>

Kindly help.

Regards,

Santosh
