As a "rookie" i am taking the floor;)
I am on tableau 9.0 an on so I will try to explain.
So upfront! I am taking starting time as a basis for my Top N calculations.
What I did:
a. Defined : Start Time Hours based on Transform > Create Custum Date > Hours
b. Defined: Duration: DATEDIFF('minute',[START_TIME],[END_TIME])
c. Defined: Rank: rank(sum([Duration]))
d. Defined: Parameter based on START_TIME, Top N
e. Defined: Show?: [Rank]<=[Top N]
Hope it is clear....
So attached is the general way to do this. In the attached I've used the 'duration seconds' as the running time (although if this isn't correct a DATEDIFF on seconds between Start and End would calculate this in Tableau), and have used the 'Week End Date' as the 'Specified Time Period'.
So first I create my RANK calculation as follows
[Rank by Duration]
I then bring this field in and set to 'compute using' Job Name. So it Ranks each job, within each 'Week End Date'.
Next I create a parameter (so I can select the Top N) and then set the following calculation, to act as a filter as the parameter changes
[Show Top N]
IIF([Rank by Duration]<=[Top N],'Show','Hide')
I bring this into the filter shelf, ensure it's compute using is 'Job Name', and select Show.
Now as we change the parameter value the list of Job Names reflects this change.
You can do a similar thing with 'incidents/Tickets created' counts, and can change the 'Week End Date' to any time dimension you need.
Hope this helps, and if not the final solution gives you the tools to get to it.

Dear Norbert Maijoor
First of all thank you so much for taking time and help me with my Stuffs, As I told you earlier also , these days I am learning so many things and technique from you. Thanks for sharing your Knowledge.I really appreciate that.
I would like to suggest something so that you can help other members as well.
1) Please keep a copy of Tableau 8.3 version we cant open Tableau 9.0
2) Or you can do some hacking and change the version of Tableau workbook from 9.0 to tableau 8.3
In addition to that, I would like to know , do the I need to create an Integer parameter (START_TIME, Top N) .Because here I am getting the Date and Time Format. So do I need to perform custom Formatting ( Like Hourly 00 ) before creating the Parameter right
Dear Norbert Maijoor
Thanks for posting the 8.3 version of tableau workbook.
It would be great if you can also help me in finding the next part of the question which is Top N jobs with most incidents/Tickets created.

As per your description, it worked like a charm but now my user wants to see the same information top 5 longest running jobs in the form of vertical bar Chart . As this chart contains all the dimension fields only , I am unable to change it into the bar chart .
