Monitor Job Satus through script

Had a need to verify prerequisite site had run prior to downstream asynchronous jobs so I found and modified a couple queries.

USE [msdb]
GO


SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

/*
Used to detemine if any jobs in a category have failed and list them
All jobs must be assigned to the same category

Parameters:
@JobCategoryName - The category name set up in hte local instance
@HoursToCheck - the number of hours back in history you want the call to look. DEFAULT = 24
@IsSuccessful - Whether or not any jobs meet the criteria
To fine all failed jobs put 0

RETURNS
Table with 
Job Name
Success or Failure status
Date Time last run

Example of a table of all failed jobs in a category
SELECT * FROM [dbo].[JobCategoryStatusList] ('SAP_to_staging', 24, 1)

CREATE FUNCTION [dbo].[JobCategoryStatusList]
(@JobCategory nvarchar(50)
, @HoursToCheck int = 24
, @IsSuccessful bit = 0
)
RETURNS @tAllJobsInStatus TABLE
(
JobName nvarchar(128)
, RunStatus bit
, LastTimeJobRan datetime
)
AS
BEGIN
--DECLARE @JobCatagory nvarchar(50) = 'SAP_to_staging';
--DECLARE @HoursToCheck int = 24;
--DECLARE @IsSuccessful bit = 1;
INSERT INTO @tAllJobsInStatus
SELECT
SJ.NAME AS [Job Name]
,RUN_STATUS AS [Run Status]
,MAX(DBO.AGENT_DATETIME(RUN_DATE, RUN_TIME)) AS [Last Time Job Ran On]
FROM dbo.SYSJOBS SJ
LEFT OUTER JOIN dbo.SYSJOBHISTORY JH
ON SJ.job_id = JH.job_id
WHERE JH.step_id = 0
AND jh.run_status = @IsSuccessful
and category_id IN (select category_id

and DATEDIFF(HH , DBO.AGENT_DATETIME(RUN_DATE, RUN_TIME), getdate()) <= @HoursToCheck
