Mapping Issue for Synchronous interface

Hi Experts,

We are facing the below issue in a SOAP to RFC synchronous scenario.

Data from WS is successfully uploaded to RFC via RFC request. However we face the below issue when the RFC response is received.

com.sap.aii.utilxi.misc.api.BaseRuntimeException:Character reference "&#00" is an invalid XML character.

We receive this error particularly when one field has the below values.

<FIELD> X 20140812201409101211 1 USD TP 00000000 </FIELD>

When we click on view source the same field shows as below:

<FIELD> &#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#12;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#12;X  20140812201409101211            1             USD     &#00;&#00;&#00;&#00;&#12;&#00;&#00;&#00;&#00;&#12;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#00;&#19;TP&#12;     00000000&#00;&#12;&#00;&#12;&#00;&#12;&#00;&#00;&#12;&#00;&#00;&#12;</FIELD>

How is a simple value getting converted to some huge value when we open it using view source.

Please help me resolving the same.

Regards,

Shai
