XSD Validation

Hello All,

I am validating Incoming xml message by selecting Validate at Integration Engine option in Sender Agreement.

The input message was properly filled with data according to XSD which is uploaded on to server.

But I am getting following err in MONI:

<SAP:Code area="XML_VALIDATION_INB">CX_XMS_SYSERR_VALIDATION</SAP:Code>

<SAP:AdditionalText>not used at the moment.</SAP:AdditionalText>

<SAP:Stack>System error occurred during XML validation</SAP:Stack>

Can someone help me

Regards,

Moorthy
