The Cloud Application Programming Model (CAP) is SAP’s framework for building enterprise-grade applications rapidly, focusing on domain-driven design and best practices. After developing a CAP application in SAP Business Application Studio (BAS), the next critical step is to deploy it to SAP Business Technology Platform (BTP) to make it accessible and scalable in the cloud.
This article provides a comprehensive guide on deploying CAP applications from BAS to SAP BTP, covering prerequisites, deployment steps, and best practices.
Before deployment, ensure you have:
Your CAP project should include:
package.json with necessary dependencies.mta.yaml or manifest.yml files describing deployment metadata.Configure environment variables or use .env files for connection parameters.
In BAS terminal:
cf login -a https://api.<region>.cf.cloud.sap -u <your-email> -o <org> -s <space>
Replace <region>, <your-email>, <org>, and <space> with your details.
Use the cf CLI or SAP BTP cockpit to provision services:
cf create-service hana hdi-shared <your-hdi-service-instance-name>
cf create-service xsuaa application <your-xsuaa-service-instance-name> -c xs-security.json
The xs-security.json file contains security role configurations.
default-env.jsonBind service instances to your app to enable connectivity.
In default-env.json, define service bindings, credentials, and environment variables as needed.
In BAS terminal, navigate to your project directory and run:
npm install
cds build/all
This prepares your app for deployment by compiling CDS files and bundling modules.
Use the Cloud Foundry CLI to deploy:
cf push
If you use an mta.yaml file (Multi-Target Application), use the MTA Build Tool to package and deploy:
mbt build
cf deploy mta_archives/<your-app>.mtar
cf apps
cf logs <app-name> --recent
Deploying CAP applications to SAP BTP via SAP Business Application Studio enables developers to deliver scalable, cloud-native SAP solutions efficiently. By following the steps outlined, you can ensure smooth deployment, proper service integration, and maintainability of your CAP-based applications in the cloud.
Leveraging BAS and SAP BTP together unlocks powerful tools for innovation, making it easier to build and deploy enterprise-ready applications.
