SOAP Runtime Protocol: SOAP Fault exception occurred in program.....Issue

Hi all,

i am using Proxy to integrate CRM to EAI. I am using extraction program to provide data to EAI from CRM.In the program i am using method of class which was generated after creating  Proxy.Then i tested the program and in tranx:SM21 i tracked the error saying

'' SOAP Runtime Protocol: SOAP Fault exception occurred in program CL_SOAP_RUNTIME_ROOT==========CP in include CL_SOAP_RU NTIME_ROOT========CM004 at position 80.

and later another Exception:'' SOAP Runtime Protocol: Exception message: Severe processing error; SOAP fault handling required''.

             I couldn't understand this exception.Is it related some kind of XSD data type or anything else?Please help me out.

             Any good solution will be rewarded.

Thanks
