Use cases

Requirements/Scope:

1. Define API through which it should be possible replace instance reference for opened order line.

Approach:
1. Define storage PATCH method
2. Refactoring

• Move following methods in the org.folio.services.lines.PoLinesService:

  • org.folio.rest.impl.PoLinesAPI#createPoLineWithTitle. And handleResponseWithLocation(asyncResultHandler, tx, "POLine {} {} created") should stay in the controller

  • org.folio.rest.impl.PoLinesAPI#updatePoLineWithTitle

  • Logic from org.folio.rest.impl.PoLinesAPI#deleteOrdersStoragePoLinesById should be moved to org.folio.services.lines.PoLinesService

    !Important : Basically all business logic should be placed in the business services

3. Define class abstractions

• Create the same class structure as in the mod-orders Class diagram

• All classes should be defined in the Spring context as singletons

Acceptance criteria:

• RAML file ramls/po-line.raml updated

• Stubs implemented

• Optional : API tests
