Building an Attachment Upload and Download Solution Using UploadSetwithTable ControlBuilding an Attachment Upload and Download Solution Using UploadSetwithTable ControlThe successor control to UploadSet posts the file in one request by default, and against CAP that is wrong: the record has to be created first and the content put to it afterwards. The author states the two-step shape plainly and notes it may not apply to an ABAP backend, which is the kind of boundary that usually goes unsaid. Written during a proof of concept for a reusable attachment component, and it carries the problem they hit with the control.published 2025-03-13

Evaluating SAP’s new MCP servers: UI5, CAP, and Fiori tools in practiceEvaluating SAP’s new MCP servers: UI5, CAP, and Fiori tools in practiceSomeone trying SAP's three new MCP servers rather than repeating the announcement. It sets the official positioning first — MCP as the bridge from coding assistants to SAP tooling across Cursor, Windsurf, Copilot, Cline and Claude Code, with best-practice scaffolds and BTP-aligned guardrails — and then reports what using them is actually like.

How I Use AI for Development and Why Context MattersHow I Use AI for Development and Why Context MattersPart one of the AI ABAP development series traces a move from pasting ChatGPT output and error messages back and forth to tools that search, read docs and inspect files themselves, and holds that the context around a model decides more in real projects than benchmark results do. In SAP work the grounding comes from mcp-sap-docs, which brings SAP Help, GitHub repositories, style guides and DSAG guidelines into the session, and context for changing a class also means the tables it uses, the classes it calls and similar implementations. Agentic autonomy is a slider set per project, with the time saved on typing moved into planning and review, and the post stops before ABAP: SAP's MCP servers for UI5, CAP and Fiori (@ui5/mcp-server, @cap-js/mcp-server, @sap-ux/fiori-mcp-server) sit in off-stack work that git and pipelines already gate, and the harder ABAP case is left to the next part.published 2026-04-20
OData to outcomes—Build AI-enabled SAP Fiori apps using SAP Fiori elementsOData to outcomes—Build AI-enabled SAP Fiori apps using SAP Fiori elementsA Fiori elements app built through SAP's MCP servers: the OData V4 service comes from the MCP server for RAP, which the atlas holds as the ADT MCP Server, or from @cap-js/mcp-server for CAP, and the UI from @sap-ux/fiori-mcp-server, with annotations and actions added before the app is tied to SAP's AI features. Agent access to your code on both the service and the UI side; SAP's abstract names the servers and the steps and says nothing about which AI features or which agent host.

Generative UIUnmapped
UI5 Has Entered the Chat: Building Interactive MCP Apps for SAPUI5 Has Entered the Chat: Building Interactive MCP Apps for SAPMCP Apps let an MCP tool point at a ui:// resource that a compatible host renders in a sandboxed iframe, and the post walks through the five samples of UI5con_2026_MCPApps, built with Mike Zaschka for UI5con, from a plain HTML time tool through UI5 Web Components and UI Integration Cards to UI5 lint findings from @ui5/mcp-server and an ARC-1 transport review. In the samples the model selects the tool and does not generate the interface, the prebuilt kind of generative UI, and the subject is the server side of MCP servers: register the resource, link it from the tool's _meta.ui.resourceUri, return text content as a fallback beside structuredContent, call callServerTool() only for tools of the server that owns the app, and send a message to the host when another server such as ARC-1 has to act. It stops at the host, whose support differs by client and whose iframe sandbox is not a complete security model, and Joule support for MCP Apps could not be verified at the time of writing.published 2026-07-13

How to consume UI5 custom libraries in BAS or VS CodeHow to consume UI5 custom libraries in BAS or VS CodeConsuming a custom UI5 library from a UI5 application locally, using yarn workspaces to resolve the dependency instead of adjusting the project before every deploy. The post is honest about its own history: the author had asked the question on SAP Community, found a workaround that needed a pre-deploy edit, and only later learned the workspace approach that removes it.

UI Composition with Application Frontend ServiceUI Composition with Application Frontend ServiceWhy shared UI code is hard, and what Application Frontend changes about it. The piece first lays out the three usual answers and what each costs — copying files at development time and repatching every consumer, publishing an npm package and rebuilding every consumer, or hosting the code separately and paying for it in CORS and session handling, or in an extra network hop through a server-side proxy. It then shows a fourth that only this service can do: runtime server-side composition without the hop, configured through routes in the consuming application's xs-app.json, across three cases — a reusable application embedded in a consumer, and two further composition shapes. Read alongside the generator, which scaffolds the mta.yaml, xs-app.json and zipper configuration this model needs.Vadim Tomnikov, published 2026-05-18

It says the SAP Cloud SDK already generates OData clients as .ts files and UI5 ships types for its controls and modules, the ground of TypeScript support in UI5, while CAP offers standard types and the new @cap-js/cds-typer generates types for a service, which is typing, with the caveat that running cds-ts commands could overwrite what cds-typer generated.MikeDoyle, published 2023-07-05
