Sometimes you need to figure out why a certain object version was or was not selected during an update. Sometimes an occurrence in the build management project hierarchies makes this necessary; other times you might need to help a developer with a problem in his development project.
If you have tried the items above, but still have selection problems, try the following:
If your projects updated correctly in the last release, but they are not updating properly in your new release, compare the process rules between the two releases.
If two projects for the same purpose and release update differently, you can compare their update properties. This is useful for a developer who is setting his update properties manually. He can see if the folders in his update properties differ from those based on templates.
Compare folder templates or folders to ensure your query is correct or to find out which members differ between two folders.
