This is a sample app for the travel reference scenario, built with the SAP Cloud Application Programming Model (CAP) and SAP Fiori Elements.

The purpose of this sample app is to:

• Demonstrate SAP Fiori annotations
• Demonstrate and compare SAP Fiori features on various stacks (CAP Node.js, CAP Java SDK, ABAP)
• Run UI test suites on various stacks

The app still contains some workarounds that are going to be addressed over time. In some cases, the model and the handlers can be improved or simplified once further planned CAP features become available. In other cases, the app itself could be improved. For example, calculation of the total price for a travel currently simply sums up the single prices ignoring the currencies.

For enabling all features of the Analytical List Page (ALP) in the Node.js runtime, we have switched on the new OData parser (odata_new_parser: true in package.json), which is still in an experimental state. Early adopters may use this feature in own projects on their own risk. You can also use the ALP with the standard OData parser, but then some features like grouping in the table are not available.

The project contains a configuration for deploying the CAP services and the SAP Fiori app to the SAP Business Technology Platform (SAP BTP) using a managed application router. The app then becomes visible in the content manager of the SAP Launchpad service.

The configuration file mta.yaml is for the Node.js backend of the app. If you want to deploy the Java backend, copy mta-java.yaml to mta.yaml.

• Create a trial account on SAP BTP. See this tutorial for more information. Alternatively, you can use a sub-account in a productive environment.
• Subscribe to the SAP Launchpad Service.
• Create an SAP HANA Cloud Service instance or use an existing one.

• Install the Cloud Foundry command line interface (CLI). See this tutorial for more details.

• Install the MultiApps CF CLI Plugin:

  cf add-plugin-repo CF-Community https://plugins.cloudfoundry.org
  cf install-plugin multiapps

• Install the Cloud MTA Build Tool globally:

  npm install -g mbt

Build the project from the command line:

mbt build

The build results will be stored in the directory mta_archives.

1. Log in to the target space.
2. Deploy the MTA archive using the CF CLI: cf deploy mta_archives/capire.sflight_1.0.0.mtar

Any authorized user has read access to the app. For further authorization, assign a role collection to your user in the SAP BTP Cockpit:

• sflight-reviewer-{spacename} for executing actions Accept Travel, Reject Travel, and Deduct Discount
• sflight-processor-{spacename} for full write access

CAP SFlight uses the managed AppRouter, which in case of a trial account, is provided by the Launchpad Service in SAP Build Workzone, Standard Edition. Please consult this tutorial to make sure that your Launchpad Service is configured correctly to serve the CAP SFlight Frontend.

You need to have access to a HANA Cloud instance and SAP BTP.

1. Deploy the HDI content to a HANA HDI container (which is newly created on first call): cds deploy --to hana.
2. Start the application with the Spring Profile cloud.
   1. From Maven: mvn spring-boot:run -Dspring-boot.run.profiles=cloud
   2. From your IDE with the JVM argument -Dspring.profiles.active=cloud or env variable spring.profiles.active=cloud

The running application is now connected to its own HDI container/schema. Please keep in mind that the credentials for that HDI container are stored locally on your filesystem (default-env.json).

The deployment to Kyma Runtime is explained in file README-Kyma-Runtime.md.
