Rational Insight tables: Why would only some Projects migrating records to RIODS, RICALM etc...

When our nightly Data Collection jobs run, we are noticing that only some projects are being included. Some Projects have their Work Items migrated over while others do not. When looking at tables such as RIODS.requests there are no corresponding records to existing work items.
It's not immediately apparent where this gets configured. Would anyone be able to explain what would cause a project's work items to be included or not included into the RIxxx tables?
Thanks in advance

Accepted answer

You probably should open a PMR - I am a user of Insight not a developer of Insight - so I am just giving you my own experience with it - sounds like you may have something else going on with your configuration.

Have you created projects since you downloaded the ETLs form the server(s)? Each project has an entry in the XDC file as a resource under the resource group. If you have added projects since you downloaded the ETLs to the Insight server those projects will not be picked up. Try downloading the ETLs again and see if your projects are picked up.

As an administrator if you go under the Reports heading for a particular application there is a Downloads section on the left that you select and configuration files for Rational Reporting Data sources - this will download a zip file for that particular application that contains the xdc files that must be added to the Insight server under <Insight Base>/etl/configs/Configurations. The xdc files have all the current projects in them and will get the data for each project. If you add new projects you need to update the xdc files or re download them from the server. You need to do this for each application you are using (rqm, rtc, rrc)
