Hey guys,
I'm new to this discussion board and quite new to BI and MSSQL.
Currently I have to solve a problem for homework in university and I don't know how to do it.
I have to build reports using Excel PowerPivot with Data out of MS SQL Server 2008. The database contains Printer-Device-Data like Errors and PageCounter.
Here is an Example of the Data:
| DateId | Severity | PageCount | DeviceId | ErrorId |
|---|---|---|---|---|
| 13.04.2012 00:00:00 | 1 | 52013 | 163 | 1 |
| 10.07.2012 00:00:00 | 1 | 56062 | 163 | 1 |
| 13.11.2012 00:00:00 | 4 | 63907 | 163 | 1 |
| 28.11.2012 00:00:00 | 4 | 64492 | 163 | 1 |
| 12.09.2012 00:00:00 | 4 | 61524 | 163 | 1 |
| 29.11.2012 00:00:00 | 4 | 64573 | 163 | 1 |
For explanation:
DateId is the Date, when an Error was raised, Severity is the Severity of the Error in general. DeviceId is the identifying Key for the Printer-Device. ErrorId identifies the Error and PageCount is the Total Page COunter at the moment when the Error raised.
My Problem is, that this counter shows the actual value. I want to extract the amount of pages, prinded between the two dates.
Any Ideas, how I can do this?
I tried to use DAX Formula with EARLIER() and PREVIOUSDAY(), but this didn't work.
Please help me.
Thank you!
