My XML file is read from Application into XI.I'm receiveing this error"<b></b>EXCEPTION DURING EXECUTION".I know this is related to MApping.I've checked my mapping and its working fine.I'm doing this scenario in BPM so will there be any problem related to integration scenario.Could any one help me in fixing out this error.

This would help me a lot.
