In 7.3, dependencies are not required between two JEE analysis units, provided that they belong to the same execution unit. That is why they are not always declared in Cast-MS.
Starting from 8.0, the behaviour of the JEE analyzer has changed : it will create links between objects belonging to different analysis units IF AND ONLY IF a dependency is declared in Cast-MS.
That is why, after migration from a 7.3.x version to a 8.y.z version, it is necessary to review the dependencies between JEE analysis units to avoid missing links.
This query, run on the 7.3.x CAST management base, will provide the list of dependencies required in Cast-MS 8.y.z to retrieve all the links that were present in 7.3.x
