Figure out whether SSIS package was executed from JOB or not

1. Write one SP, like this -
   ALTER PROCEDURE [dbo].[RunDTSPackages]
   @JobID VARCHAR(255)
   AS
   BEGIN
   SET ROWCOUNT 0
   DECLARE @DtexecQuery VARCHAR(8000)
   DECLARE @PackageName VARCHAR(200)
   DECLARE @DatabaseServer VARCHAR(100)
   DECLARE @ID INT
   DECLARE @JobSYSID VARCHAR(255)
   DECLARE @ReturnCode INT
   ----my package name to BLANK initially
   SET @PackageName = ''
   ----my server name
   SET @DatabaseServer = 'F1LT230'
   --Passing the SysJobID
   SET @JobSYSID ='/set \package.variables[SysJobID].Value;"\"'+@JobId+'\""'
   DECLARE @tblSSISMaster TABLE(
   ID INT PRIMARY KEY,
   Name VARCHAR(255),
   PackageName VARCHAR(255)
   )
   INSERT @tblSSISMaster SELECT
   ID,
   Name,
   PackageName
   FROM SSISPackageToRun
   WHERE IsMaster = 1 ORDER BY ID DESC
   SET ROWCOUNT 1
   SELECT @ID = ID FROM @tblSSISMaster
   WHILE @@ROWCOUNT <> 0
   BEGIN
   SELECT @PackageName = LEFT (PackageName, LEN(PackageName)-5) FROM @tblSSISMaster WHERE ID = @ID
   SET @DtexecQuery = 'dtexec /sq ' + @PackageName + ' /ser ' + @DatabaseServer + ' '
   SET @DtexecQuery = @DtexecQuery + @JobSYSID
   --Print @DtexecQuery
   EXEC @ReturnCode = xp_cmdshell @DtexecQuery
   DELETE FROM @tblSSISMaster WHERE ID = @ID
   SELECT @ID = ID FROM @tblSSISMaster
   END
   SET ROWCOUNT 0
   END
2. Create a job and call above SP as under. Also ensure that you are logging the GUID generated from the job. Also, if same package is being executed from other way - using WEB App or directly, pass a hard coded GUID.
   DECLARE @SQL NVARCHAR(72), @jobID UNIQUEIDENTIFIER, @jobName SYSNAME
   SET @SQL = 'SET @guid = CAST(' + SUBSTRING(APP_NAME(), 30, 34) + ' AS UNIQUEIDENTIFIER)'
   EXEC sp_executesql @SQL, N'@guid UNIQUEIDENTIFIER OUT', @guid = @jobID OUT
   EXEC RunDTSPackages @jobID
3. Query the log table for the above two unique GUIDs and get the reports generated as in to know whether the package was executed from the Job or Web.
4. Your log table should have following columns -
   ExecutionLogId]
   ,[ParentExecutionLogId]
   ,[Description]
   ,[PackageName]
   ,[PackageGuid]
   ,[MachineName]
   ,[ExecutionGuid]
   ,[LogicalDate]
   ,[Operator]
   ,[StartTime]
   ,[EndTime]
   ,[Status]
   ,[FailureTask]
   ,[tblsysJobID]
