Thanks a lot, that clarify it. When you say the level should be
regenerated, is this some kind of SQL trigger or it is a check/update the
app does itself on start ? I was thinking to update those manually too
(does not looks like a lot).

Your script is actually handy to already check any link between the org
unit to be deleted and the rest of the application - I suppose your list of
delete should be all links there, so I can use it as a check.
