Find jobs that succeeded, but had steps that failed
You need to analyze data in the jobstephistory table.  

You can use following query, it is slightly modified script from Analyzing SQL Agent Job and Job Step History in SQL Server by Atif Shehzad:

--Script # 1: To generate steps history of all jobs USE msdb GO

SELECT j.name JobName,h.step_name StepName,
CONVERT(CHAR(10), CAST(STR(h.run_date,8, 0) AS dateTIME), 111) RunDate, 
STUFF(STUFF(RIGHT('000000' + CAST ( h.run_time AS VARCHAR(6 ) ) ,6),5,0,':'),3,0,':') RunTime, 
h.run_duration StepDuration,
case h.run_status when 0 then 'failed'
when 1 then 'Succeded' 
when 2 then 'Retry' 
when 3 then 'Cancelled' 
when 4 then 'In Progress' 
end as StepExecutionStatus, 
case jobsts.run_status when 0 then 'failed'
when 1 then 'Succeded' 
when 2 then 'Retry' 
when 3 then 'Cancelled' 
when 4 then 'In Progress' 
end as JobExecutionStatus, 
h.message MessageGenerated
FROM sysjobhistory h inner join sysjobs j
ON j.job_id = h.job_id and h.step_id !=0
inner join sysjobhistory jobsts
on j.job_id = jobsts.job_id and jobsts.step_id =0
WHERE 
jobsts.run_status = 1
and h.run_status != 1
ORDER BY j.name, h.run_date, h.run_time
