Create a new package called Derived columns are better.  Within this create a single data flow task as follows:

The data flow task with script

The task should import rows from the Series worksheet in the Excel workbook in the above folder, then use a script component to set the value of a new column called RunLength to equal the duration of each series in days (see below for code excerpt).  Finally, the task should use Union All as a dead-end destination, and display the results in a data viewer on the pipe leading to this.


Here's some sample code to work out the difference between two dates in days, which may help you:

// take the time difference, and convert it into days

Row.RunLength = (Row.Finishdate - Row.Startdate).Days;

When you run your package, you should see this in the data viewer:

Data viewer results

The first few series in the data viewer, showing the length of the series in days.


Final thought: why do you suppose that this exercise suggests giving the package the name it does?
