Building a SaaS Multitenant Application Using SAP CAP Framework — Without a DatabaseBuilding a SaaS Multitenant Application Using SAP CAP Framework — Without a DatabaseMultitenancy with the database taken out, which is a useful way to see what is left: the approuter and its tenant host pattern, the XSUAA instance in shared tenant mode, and the SaaS Registry binding that makes a subscription happen. Everything here is subscription lifecycle and routing, so the parts that are usually entangled with HDI container provisioning are visible on their own.DebashishDas, published 2026-05-06
Building SaaS Products on SAP BTPBuilding SaaS Products on SAP BTPAn architecture essay rather than a build, written against SAP's own ABAP Cloud Partner Reference App material and explicitly extending it. Part one of a pair; the second is where the hard problem is.michal_majer, published 2025-09-30
Designing a Multi‑Tenant Solutions on SAP BTP – Architecture and Prototype WalkthroughDesigning a Multi‑Tenant Solutions on SAP BTP – Architecture and Prototype WalkthroughWritten back from a delivered project, and it lists the constraints that shaped it rather than the features that showcase it — several customers, strict data isolation, central lifecycle management, and operations kept simple.Avinash_Vaidya, published 2026-02-17
Event-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshEvent-Driven Multi-Tenant Architecture on SAP BTP with CAP and SAP Event MeshThe two topics that are usually written about separately, taken together — because a shared broker is where tenant isolation stops being automatic. It starts from why microservices are decoupled at all, places Event Mesh among the four broker services BTP offers, and then works through what changes when the publisher and the consumer are multitenant.ale_biagi, published 2024-12-19
Kyma Evolution: Transforming SAP Kyma into a tailor-made SaaS Platform for sbs extensionsKyma Evolution: Transforming SAP Kyma into a tailor-made SaaS Platform for sbs extensionsWritten by an extensibility expert building against Cloud ERP under clean core, and it treats Kyma as something to shape rather than to adopt — what has to be added to the runtime before it is a SaaS platform for CAP extensions. The Partner Reference Application post is the hands-on sequel.ChristianWeiss, published 2026-02-03
Multitenant MTA: providing a Cloud Portal Service with FIORI apps to subscriber accountsMultitenant MTA: providing a Cloud Portal Service with FIORI apps to subscriber accountsFiori applications reaching a subscriber's own launchpad, which is the part of multitenancy the runtime does not do for you. The author's motivation is that the information exists but is scattered across documentation, and this puts it in one place.former_member1760, published 2022-01-03
Multitenant SaaS applications on SAP BTP using CAP - The Reloaded Version!Multitenant SaaS applications on SAP BTP using CAP - The Reloaded Version!An announcement rather than a tutorial, and it is the one that changes how the rest of the series should be read: the Cloud Foundry and Kyma code lines and their documentation were merged into a single sample, so the runtime becomes a choice inside one repository instead of a fork in the reading path.martinfrick, published 2023-08-09

SAP BTP, Kyma Runtime!The Kyma counterpart to the Cloud Foundry Tried-and-True series — the same SaaS application, the same requirements, a Kubernetes runtime underneath. The two code lines were later merged, which the Reloaded post announces.martinfrick, published 2023-04-05
Multitenant SaaS applications on SAP BTP using CAP? Tried-and-True!Multitenant SaaS applications on SAP BTP using CAP? Tried-and-True!The opening post of the Cloud Foundry series, and the one that states the shape of the whole thing: a sample built out of a partner co-innovation project with BCG, then delivered in three graded versions — Basic, Advanced, Expert Features — against a fictional partner's requirements. Read it for the motivation and the map; the implementation is in the three that follow.martinfrick, published 2022-10-19
Multitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Advanced VersionMultitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Advanced VersionWhat the basic version leaves out and production needs: central user management, and reaching an on-premise S/4HANA from a subscribed tenant. Framed as a step towards production readiness rather than as production itself, which is the honest reading — the Expert Features post is where the rest of that distance is covered.published 2022-11-21
Multitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Basic VersionMultitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Basic VersionThe version deliberately bounded by what a trial or pay-as-you-go account can hold — the authors point out a PAYG owner can run it for nothing on free-tier services. Scenario first, then the architecture diagram, then a component-by-component walk through what each service in it is for.published 2022-10-24
Multitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Expert FeaturesMultitenant SaaS apps on SAP BTP using CAP? Tried-and-True! – The Expert FeaturesThe last of the four, and the one carrying the features that are optional until they are not. Each is written up as a self-contained tutorial in the sample repository rather than inline, so the post is a guide to which of them applies to your landscape.martinfrick, published 2022-11-29

SaaS Self-Onboarding and One-Domain Concept in SAP BTP, Kyma Runtime using CAPSaaS Self-Onboarding and One-Domain Concept in SAP BTP, Kyma Runtime using CAPTwo requirements that only appear once a SaaS application has customers: subscribing a tenant end-to-end without the provider doing it by hand, and serving every tenant from one domain instead of one host per subscriber. Kyma runtime, and the post is a summary pointing at an Expert Feature tutorial in the sample repository — it says so itself, offering a one-minute read as the entry point.martinfrick, published 2023-06-01

TelemetrySAP and community
SAP Cloud Logging Serviceでコンテナメトリクスを監視するSAP Cloud Logging Serviceでコンテナメトリクスを監視するIn Japanese. Container metrics for a CAP Node.js application into SAP Cloud Logging Service, and the reason it exists is that the obvious route does not apply: Spring Boot Actuator covers the Java side, and Node has no equivalent, so the author reaches for Telegraf instead. The procedure is deliberately independent of application logic — bind the instance, add a startup script and a config file — so it works against an application you already have.kyoneo, published 2024-03-26

Making CAP Application Development Easier and Faster with the Help of Storyboard in SAP Business Application StudioMaking CAP Application Development Easier and Faster with the Help of Storyboard in SAP Business Application StudioThe Storyboard from the other side — someone who came across it while learning the high-productivity tools, rather than someone who shipped it. It follows the whole arc a CAP project takes through the tool: entities, relationships, services, sample data, a UI, roles, and external resources, each as a thing the diagram can add rather than a file you open.Aryan_Raj_Sinha, published 2023-09-20
Migrating Your CAP Applications from SAP Web IDE to SAP Business Application StudioMigrating Your CAP Applications from SAP Web IDE to SAP Business Application StudioA migration checklist, and a reminder of how much of a CAP project used to be editor-specific: Web IDE configuration files to delete, a build to move to the Cloud MTA Build Tool, a CAP Java version to raise. Historical — Web IDE is gone — but it is the clearest list of what the tooling boundary used to include.liat_b, published 2020-07-09

Simplifying SAP BTP Authentication in Pipelines with SAP Passport and PlaywrightSimplifying SAP BTP Authentication in Pipelines with SAP Passport and PlaywrightClient-certificate login to BTP works locally and has historically not worked in automated pipelines. The post uses Playwright's then-new client certificate support to close that, which is a sideways use of a browser automation library and the reason it is worth recording — the constraint it removes is a CI constraint, not a testing one.published 2024-11-08

Testing SAP Build Process Automation task UI in SAP Business Application StudioTesting SAP Build Process Automation task UI in SAP Business Application StudioA task UI built from the Workflow Task UI template cannot be run in Business Application Studio: it expects the task model and the inbox API as startup parameters, and without them it fails before the view renders. The post shows the error, explains why it happens, and supplies a wrapper that provides the missing context locally, so the alternative to deploying on every change is not deploying on every change.published 2023-10-15
