The ERM module contains tables configurable via Table settings. The chapter in the manual needs mentions of each of these tables. The table names should also be added to the Admin > Table settings page.
Added cross-references in ERM chapter to the table settings for tables id: agreements, licenses, titles, packages (Merge request https://gitlab.com/koha-community/koha-manual/-/merge_requests/868). Awaiting clarification regarding tables id: usage_data_providers, counter_logs, monthly_usages and yearly_usages.
