Required document structure

When you examined each travel document, you identified pages that are required and optional.

For example, in car rental documents:
  • The rental agreement page is required.
  • The insurance page is optional.
For travel documents with multiple pages, requirements might be necessary for the number or order of pages of each document type. This table summarizes the structure of each travel document type.
Document Type Page Type Number Required? Order
Car Rental   Any number per batch No Any position within batch
  Rental Agreement One per document Yes Must be first in document
  Optional Insurance One per document No Must be second in document
Hotel   Any number per batch No Any position within batch
  Room_Receipt One per document Yes Must be first in document
  Meals Any number per document No Cannot be first in document
  Other_Charges Any number per document No Cannot be first in document
Flight   Any number per batch No Any position within batch
  Air_Ticket One per document Yes Must be first in document
This structural information is an important element of the design requirements that you use when you implement the application's document hierarchy. When you implement the document assembly stage of the workflow, you use this information to determine whether the pages in the batch meet the structural requirements.
The assumption for the sample application is that you are entering batches of mixed travel documents with multiple, consecutive pages that are in the correct order. For example, a batch might include any number of car rental documents, flight documents, and hotel documents. Also, the pages within each document are consecutive and in the correct order. If the batch meets the structural requirements, then the application assembles the documents automatically. However, if the batch contains orphan pages or pages that do not meet the rules for document integrity, then operator intervention is necessary.
In the following example, the batch does not contain any errors, and no operator intervention is needed.

In this second example, the batch contains three errors and requires operator intervention.

  1. Orphaned optional insurance page must follow a rental agreement page.
  2. Orphaned meals page must follow a room receipt page.
  3. Two optional insurance pages are not allowed in a Car Rental document.
