I have been asked to create a report which basically lists all the changed source files relating to a Project (Or work Item) I know that IBM do not allow access to that area of the database but was hoping that there may be a premade query or something that I could use. I have found the link below which lists all the premade reports but when I went to the relevant location (com.ibm.team.examples.reports.common) some of those .rptdesign files weren't present. the folder did have a version attached to it (com.ibm.team.examples.reports.common_3.1.500.v20131025_0102) is this the latest version of this file? if not, where can I get the latest version? and am I going the right way to make this report?
