To check if the row already exists you can do

If Exists (Select Top 1 1 from tblPurpose where Purpose = @Purpose and [Type] = @Type)
Begin
   Insert Into tblPurpose
     (Purpose, [Type])
   Select 
     @Purpose, @Type

   SET @Result = 'Inserted'
End
Else
Begin
   SET @Result = 'Record exists'
End
