ASKER

the formatter threw an exception while trying to deserialize the message:Error in deserializing body of request message for operation 'CalculateMediSave'.The maximum string content length quota (8192) has been exceeded while reading XML data.This quota may be increased by changing the MaxStringContentLenght property on the XmldictionaryReaderQuotas object used when creating the XML reader Line 273,position 35.
