Before starting
The analytical sections and their sections are to be archived in the settings wheel at the top right and then in Analytical sections.
Archiving an analytical section
You can no longer delete an analytical section once a user has been attributed to it. Then, you will only be able to archive it and thereby prevent any attribution to this element. Such an action will affect all the solutions that use this section.
Archived sections can be displayed using the filter above the list of sections.
You can then reactivate sections that have been archived.
