Hi,
I am pretty new to Web Intelligence and use to reporting in Excel.
I have a universe that is using SQL to pull data into a derived table within a universe
the Table Output is Process ID, Ticket Month and Month Closed
Example
| Process Id | Ticket Month | Month Closed |
| IM-000583 | 201307 | 201308 |
| IM-000584 | 201307 | 201308 |
| IM-000587 | 201307 | 201309 |
| IM-000588 | 201307 | 201308 |
| IM-000590 | 201308 | 201308 |
| IM-000592 | 201308 | 201308 |
| IM-000593 | 201308 | 201308 |
| IM-000594 | 201308 | 201308 |
| IM-000595 | 201308 | 201308 |
| IM-000596 | 201308 | 201308 |
| IM-000597 | 201308 | 201309 |
| IM-000598 | 201308 | 201308 |
| IM-000600 | 201308 | 201308 |
| IM-000601 | 201308 | 201308 |
| IM-000602 | 201308 | 201308 |
| IM-000603 | 201308 | 201308 |
| IM-000604 | 201308 | 201308 |
In Excel I am able to use the count if function to Count Tickets Opened In a Month, tickets Closed in a month and then Calculate the backlog
Example
| Total Opened | Total Closed | Total Backlog | |
| 201505 | 2129 | 2149 | 723 |
| 201506 | 2134 | 2222 | 635 |
| 201507 | 1625 | 1693 | 567 |
| 201508 | 1574 | 1523 | 618 |
| 201509 | 1941 | 1711 | 848 |
| 201510 | 2672 | 2566 | 954 |
| 201511 | 2242 | 2393 | 803 |
| 201512 | 1802 | 1805 | 800 |
| 201601 | 1789 | 1732 | 857 |
| 201602 | 1901 | 1895 | 863 |
| 201603 | 1750 | 1825 | 788 |
| 201604 | 1674 | 1650 | 812 |
Backlog for the current month (201604) is a count of all open tickets (812) ie Month Closed = Blank
Previous months Backlog is calculated by taking the Previous Backlog - ( Total Opened - Total Closed)
So for 201603 = 812 - (1674 - 1650) = 788
201602 = 788 - (1750 - 1825) = 863 etc
This can then be graphed.
The issue I have is that in WEBI I can count the tickets opened in and count the Tickets Closed but I can not subtract one from the other to find the back log.
Any hints/tips/advice to emulate the above report in WEBI would be much appreciated. I have also attached the Data straight out of the universe in case that helps.
