Table Mapping in Entity Frame work with Sql Store Procedure.

I have Insert Sql procedure in SQL Database. I want to map this sql store procedure in Entity Frame Work Table Mapping with Insert Function. Problem here is procedure is having three output parameter which should get mapped in Table Mapping of EF. Please also write small function where [login to view URL]() is called and function is able to receive the 3 output Paramter. I have attached the Insert Store Procedure along with this project also the screen shot of Table Mapping there Store Procedure should be Mapped. and You have need to make one function where if user can do [login to view URL](SalesorderHeader); and [login to view URL](); some how we should be handle the there output Parameter ( @NewCode , @ErrorCode , @ErrorDesc ) in VS.
