com.sap.aii.utilxi.misc.api.BaseRuntimeException:An invalid XML character (Unicode: 0x1f) was found in the element content of the document

Hi,

I'm getting the below runtime exception during IDOC- SOAP message mapping in Integration engine.

"Runtime exception occurred during application mapping com/sap/xi/tf/<<<\\Message mapping object name\\>>>; com.sap.aii.utilxi.misc.api.BaseRuntimeException:An invalid XML character (Unicode: 0x1f) was found in the element content of the document"

I have no clue why this exception occurs. Could anyone say the reason of the exception?

Thanks!

Regards,

Gopi
