Current situation or problem: ECS is not currently able to support title level requests (TLR) between tenants

In scope: A solution that provides the ability for institutions using enhanced consortia support set up to also utilize title level request functionality.
Note: While investigating requirements and scope to support title level requests in a FOLIO only multi tenant environment, we discovered that item level requests need to be supported, too. This feature covers the ability for cross tenant circulation for item and title level requesting.

Out of scope

Use case(s): 
A library has it's FOLIO instance set up with ECS/multiple tenants. They want to support the ability to fulfill requests from multiple locations from a title (and item) level.

Proposed solution/stories

This feature covers the “happy path” of title (and item) level request fulfillment. This includes the following:

• Adjusting Circulation settings to allow for the enablement of ECS TLR at the central tenant level to support multi-tenant title (and item) level requests

• The ability for data tenants to enable/disable TLR to allow (or not) title level requests within the data tenant

• Basic ring-down logic to support TLR (and item) fulfillment across data tenants

  • mod-tlr calls mod-search to get information about the items of the requested instance (title)

  • mod-search responds with information about the items, including statuses and tenants for each item

  • mod-tlr sorts all of the received tenants in the descending order using this criteria:

    • number of the "Available" items

    • number of the items "Checked out" or "In transit"

    • number of items

  • mod-tlr goes through the sorted list of tenants and tries to place a TLR request until it either succeeds or runs out of tenants
