In Settings->Tenant->Campuses/Libraries/Institutions/Locations/Service points, a maximum of 3000 items can be displayed. Shanghai Library hopes to make this limit configurable in order to load more items. This might also apply to Circulation rules and other settings.
On the aforementioned interfaces, folio prefetches all parameters in advance. When there are many parameters, it takes a long time to initialize the pages. It would be ideal to load them interactively with multiple steps, e.g. if we click on a parameter, then only the subordinate parameters will be read, as shown in the second screenshot, we first request institution, then campus, and at last libraries. This will avoid loading all the data at once.
The interfaces crashed when Shanghai Library changed the limit from 3000 to 20000.
A temporary solution on plan is to redo the interface managing circulation rules, locations and service points. Create a new interface to accomplish the tasks.
