I tried adding msdb.dbo.sp_add_jobserver to my start procedure

ALTER PROCEDURE [dbo].[StartBookingReminders]

-- Add the parameters for the stored procedure here

@RunsEvery Int,

@ServerName VARCHAR(30),

@DatabaseName VARCHAR(128)

AS

BEGIN

Exec dbo.StopBookingReminders

exec msdb.dbo.sp_add_job @job_name = 'CS-Booking_Reminders',

@enabled=1

exec msdb.dbo.sp_add_jobstep

@job_name = 'CS-Booking_Reminders',

@step_name = 'Check for reminders to send',

@subsystem = 'TSQL',

@command = 'exec dbo.SendBookingReminders',

@database_name = @databaseName

exec msdb.dbo.sp_add_schedule

@schedule_name = 'CS-Booking_Reminders_Schedule',

@enabled = 1,

@freq_subday_type = 8,

@freq_type = 128,

@freq_subday_interval = @RunsEvery

exec msdb.dbo.sp_attach_schedule

@job_name = 'CS-Booking_Reminders',

@schedule_name = 'CS-Booking_Reminders_Schedule'

exec msdb.dbo.sp_add_jobserver

@job_name = 'CS-Booking_Reminders',

@server_name = @ServerName

END

Haven't seen any results in the job history yet

SELECT

*

FROM

msdb.dbo.sysjobhistory AS JH JOIN

msdb.dbo.sysjobs AS J

ON JH.job_id = J.job_id

WHERE

J.NAME = 'CS-Booking_Reminders'
