I have flagged certain tasks as 'communications' throughout my plan, and created a report filtered by this flag.
When i sort by date however MS projects tries to keep the outlining structure as well as sort by date. In MSP 2010, there was an option to turn this off so it sorted purely on date. However in the version of MSP 2013 i am working on, this isnt the case and the report is useless without any kind of sorting.

Does any one know how to take out the option to sort by the outline structure in MSP 13?
