I am in PPM 9.3 and was trying to purge a year old data for particular proposal and project type. Everything was better in the purging screen as i was able to select the correct proposal and project types. But when i run it, the projects are not getting deleted saying it is dependent on proposal. So i tried deleting the proposal and it shows msg that it is dependent on project. i tired both together and it is same message.
Did anyone had successfully purged old proposals and projects
Did the dependencies that popped up referred to entities that were also scheduled for purging?
One thing to understand about PPM purging is that it's not aimed at deleting a small, specific set of objects, because there are lots of entities relations in PPM, and the purging tool will prevent deletion of any entity with relations to live entities not scheduled for deletion.
The most efficient way to use it goes along the lines of "Delete everything that was create more than 3 years ago".
If you try to do stuff like "delete all projects created by user X", then it's very likely that there'll be plenty of references to live objects that will prevent this from happening.
