SysOperation Multithreading - AX 2012

//This is a service class which runs controller that has contract( with query as a parameter) , service class and that can be multi threaded to run parallel process.
multi threading will improve the performance when you process larger number of records and consume less time than the normal sysoperation controller class process.
