Connect S4 public cloud with Build process

2025-11-24T13:49:24.005000+01:00

Hi everyone,
I would like to ask for your help. I am trying to create a process and use it in our S/4HANA Public Cloud system.

I’ve added an approval step to my process; however, I can see the approval message only in my Build Inbox and not in the S/4 system inbox, even though the system user was added as a recipient.

The process was deployed to the destinations with the additional properties.

Upload a file in SAP Build apps

2025-11-28T04:50:58.215000+01:00

Upload a file using SAP Build apps

Hello All,

Hope you are doing well.

I am creating a web application using SAP build apps in which I want to pick file from local filesystem and pass the content of the file to a LLM configured using AI core .

I tried using the Pick Files component available in market place for achieving the upload part and was able to do so but as mentioned in the official documentation the component does not support web platform.

Can you guide me how I can have this functionality for web application.

Thanks & regards,

Pankaj Gupta

@cap-js/mcp-server - Practical guide to get value on day on

2025-11-30T15:04:04.883000+01:00

Give your coding assistant instant, project‑aware knowledge of your CAP model and docs. With @cap-js/mcp-server, the assistant can look up entities, services, fields, and HTTP endpoints from your compiled CDS model and cross‑check official CAP docs, so it proposes the right code and changes in your editor.

Here's where I found this and would like to share with community - https://github.com/cap-js/mcp-server

Package: @cap-js/mcp-server
Command: cds-mcp
Tools: search_model (compiled CDS/CSN), search_docs (local CAP docs embeddings)
Works with MCP‑capable assistants in VS Code and other IDEs (e.g., Cline, Copilot Agent Mode, opencode)

Here’s the short version - just follow these 3 step

Configure your IDE agent to start the server via npx:

{
  "mcpServers": {
    "cds-mcp": {
      "command": "npx",
      "args": ["-y", "@cap-js/mcp-server"],
      "env": {}
    }
  }
}

Add these rules to AGENTS.md so the assistant always uses the server correctly:

- You MUST search for CDS definitions, like entities, fields and services (which include HTTP endpoints) with cds-mcp, only if it fails you MAY read *.cds files in the project.
- You MUST search for CAP docs with cds-mcp EVERY TIME you create, modify CDS models or when using APIs or the `cds` CLI from CAP. Do NOT propose, suggest or make any changes without first checking it.

Optional CLI smoke test:

npm i -g @cap-js/mcp-server
cds-mcp search_model . Books entity
cds-mcp search_docs "how to add columns to a select statement in CAP Node.js" 1

Why you’ll love it

Stop guessing: Fuzzy‑search your compiled model for entities, services, elements, annotations, and endpoints.
Fewer mistakes: Suggestions are grounded in your actual model and verified against official CAP docs.
All local: Fast and private, perfect for day‑to‑day development.

IDE setup

VS Code - Cline extension

Settings example:

{
  "mcpServers": {
    "cds-mcp": {
      "command": "npx",
      "args": ["-y", "@cap-js/mcp-server"],
      "env": {}
    }
  }
}

VS Code - GitHub Copilot Agent Mode (global mcp.json)

{
  "servers": {
    "cds-mcp": {
      "command": "npx",
      "args": ["-y", "@cap-js/mcp-server"],
      "env": {},
      "type": "stdio"
    },
    "inputs": []
  }
}

opencode

{
  "mcp": {
    "cds-mcp": {
      "type": "local",
      "command": ["npx", "-y", "@cap-js/mcp-server"],
      "enabled": true
    }
  }
}

Tip: Keep the server name “cds-mcp” in both your config and prompts so your assistant reliably calls it.

How to use it in your editor

Think “discover first, then change.” Ask your assistant to:

Discover model and endpoints
- “Use cds‑mcp search_model to list all services and their HTTP endpoints. Then list entities with primary keys.”
Write a correct SELECT with expand
- “Call cds‑mcp search_model for Books and its associations. Then, after checking CAP Node.js SELECT expand syntax via cds‑mcp search_docs, propose a handler that returns Books.title, Books.stock and expands auther.name.”
Generate precise OData URLs
- “Find the service and endpoint for Books via search_model, then give me an OData V4 URL with $select=title,stock and $expand=author($select=name) plus a curl example.”
Safely change CDS/annotations
- “Show docs for @Common.Label using cds‑mcp search_docs. Using search_model for Books, propose a minimal diff adding labels for title and stock. Include file paths.”
Plan a refactor
- “We’re renaming Author to Writer. With cds‑mcp search_model, list affected entities, associations, services, and endpoints; propose a step‑by‑step PR plan.”
Implement an action/handler
- “Find docs on defining and implementing a custom action in Node.js via cds‑mcp search_docs. Then sketch a minimal handler in srv/<service>.js with imports and input validation.”

Best practice: Ask the assistant to paste the search_model and search_docs results that justify any change.

CLI usage (optional but handy)

Install globally to test from your terminal:

npm i -g @cap-js/mcp-server

Search your compiled model:

cds-mcp search_model . Books entity

Search CAP documentation:

cds-mcp search_docs "how to add columns to a select statement in CAP Node.js" 1

Once the CLI works, your IDE agent can invoke the same tools automatically.

What the tools return

search_model
- Names and kinds (entity, service, etc.)
- Elements and annotations
- File locations
- HTTP endpoints where services are exposed
search_docs
- The most relevant CAP documentation snippets for your query, based on local embeddings

Use both together: discover exact names/paths with search_model, confirm syntax and best practices with search_docs, then apply small, reviewable changes.

Tips for getting the most value

Start every task with search_model to avoid typos and stale assumptions.
Require docs‑backed edits: have the assistant run search_docs before proposing code.
Keep edits atomic: one focused change at a time, with file paths and minimal diffs.
Monorepo? Tell the assistant the CAP project folder to search.

Now action -

Add the MCP config, paste the two rules into AGENTS.md, and ask your assistant:

How to apply a filter on a single property of a data set using more than one value of this property

2025-12-13T13:36:58.241000+01:00

Hi,

We need to filter a data entity using the filter conditions input of a "Get record collection" activity in Build Apps. For this, we use the following formula in the Formula Editor:

{type: "and", conditions: [{type: "eq", property: ["account.id"], value: appVars.collectedAccountTechnicalIds[0].accountTechnicalId}]}

appVars.collectedAccountTechnicalIds is the variable where we store the values needed to filter the data set. It is a list of objects with one property (accountTechnicalId).

The formula works well, but as you can see, we're filtering using the first occurrence of the array only ([0]), which results in showing the records filtered on this value only. We've made countless tests but they're always returning errors, for instance:

{type: "and", conditions: [{type: "eq", property: ["account.id"], value: appVars.collectedAccountTechnicalIds}]}

So the question is: using the Formula Editor, is there a simple way to apply the filter using all the values stored in the variable? Else, is there some sort of "for each" activity or should we create a loop or use a JS script in the logic canva? Basically, the goal here is to apply a filter on a single property of a data set using one or more values of this property.

Thanks a lot for your help on this, we're stuck on this problem for quite some time now and we need to implement this urgently for a demo to a client next Thursday...

Best regards,

LM.

Issues Migrating from DEV to QAS Using CTMS with SAP Build Apps and SAP Build Process Automation

2025-12-19T15:39:09.915000+01:00

When using SAP Build Apps and SAP Build Process Automation,
I encountered issues migrating from the DEV environment to the QAS environment via CTMS.
It seems the problem is related to the scheme version, as the release process fails.

As a workaround, I tried changing the scheme version before releasing, but I couldn’t find a successful method.
In SAP Build Process Automation, I even had to remove all dependencies to import the package, which is not ideal.

Is there any effective way to handle this migration without removing all dependencies or facing scheme version conflicts?
Any best practices or recommendations would be greatly appreciated.

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

SAP Build AppsやSAP Build Process Automationを使用して、CTMSでDEV環境からQAS環境へ移送しようとした際、
scheme versionの影響と思われる問題でリリースがうまくできませんでした。

対策としてscheme versionを変更してリリースを試みましたが、成功する方法が見つかりませんでした。
特にSAP Build Process Automationでは、パッケージをインポートするために依存関係をすべて削除する必要があり、
非常に非効率的です。

依存関係を削除せず、scheme versionの問題を回避して移送する良い方法やベストプラクティスはありますでしょうか？
アドバイスをいただけると幸いです。

How use HTTP destination request with GOS?

2026-01-24T16:46:48.624000+01:00

Hello,
I have an issue that I am facing with a button functionality implemented using the Flow
Function ‘HTTP destination request’ in SAP Build Apps.

Context
I am developing an application in SAP Build Apps that needs to upload attachments to
S/4HANA using the standard OData service API_CV_ATTACHMENT_SRV.
The upload is triggered by a button press in the UI, and the attachment is selected by the
end user.
I am following an SAP blog that explains how to upload attachments from SAP Build Apps
using the HTTP Destination Request component. In the blog, the implementation is done
using DMS (Document Management Service) and the approach works correctly, including
the CSRF handling and multipart/form-data POST request. In my case, I cannot use DMS
and I need to upload attachments using GOS (Generic Object Services) via the standard
OData service API_CV_ATTACHMENT_SRV. I am trying to adapt the same approach shown
in the blog to GOS, but this is where I am currently blocked with the 403 Forbidden error.

Source: https://community.sap.com/t5/technology-blog-posts-by-sap/connect-sap-build-apps-with-dm
s-free-projects-videos/ba-p/13986096

I used the same destination configuration as described in the blog.

The only difference in the destination details is the Proxy Type, which is set to ‘Internet’ and in my case is OnPremise.

------

In the Request body i send key: media with value: <picture jpg>

Path: /sap/opu/odata/sap/API_CV_ATTACHMENT_SRV/AttachmentContentSet
Headers with the relative value:
● Slug: (Slug of the image)
● LinkedSAPObjectKey: (LinkedSAPObjectKey data from a Notification created
before this)
● BusinessObjectTypeName: BUS2038
● Content-Type: image/jpeg

If I press F12 and look at the network tab I can see the Response, the error 403 Forbidden.

But then If I tried with Postman it works.

And on the S/4HANA usign the transaction /IWFND/TRACES I can see an error exactly on
the moment when a HEAD request is executed

Someone have a clue about this?
Thanks

Is SAP Build subscription alone sufficient to create mobile applications, or is SAP Build Apps subsc

2026-02-02T07:47:40.296000+01:00

As per SAP documentation, SAP Build is a bundle that includes the following services:

SAP Build Apps
SAP Build Process Automation
SAP Build Work Zone

I would like to clarify the licensing and subscription aspect.

If we subscribe only to SAP Build, is that sufficient to create and deploy mobile applications using SAP Build Apps?

Or do we need to purchase/subscribe to SAP Build Apps separately, even though it is part of the SAP Build bundle?

It would be helpful if someone could explain:

Whether SAP Build Apps is automatically included with SAP Build

Or if it requires an individual subscription/entitlement

Any limitations (users, runtime, mobile deployment) with SAP Build Apps under SAP Build

Thanks in advance for your guidance.

BPA Unable to verify the signature of the archive (Transport Joule Skills)

2026-02-04T23:03:54.488000+01:00

Hi guys, could anyone help me out?

In SAP Build Process Automation (BPA), I’m trying to migrate/transport a Joule Skill project from Subaccount A (US, Azure) to Target Subaccount B (another region, US VA, AWS).

The import fails with this error:

Unable to verify the signature of the archive. Make sure the landscape keys from landscape us21-prod are imported in your landscape, if not, contact DevOps. Ensure that the other potential reasons for this error are checked. This error could happen for the following reasons: Couldn't get key xxxxxxxxxxxxxxxxx version from credential store.

The same error - Transport and Upload proyect.

I’ve searched everywhere and couldn’t find anything useful.

I did find an SAP Note that suggests using a tenant in the same region, which is honestly very limiting because it would force us to change our entire landscape design just because of BPA:

https://me.sap.com/notes/3472593/E

Has anyone found a way to solve this (e.g., importing landscape keys / fixing credential store key access) and successfully transport BPA/Joule projects across regions?

I already opened a ticket with SAP, but I haven’t received an answer yet.

Thanks a lot!

Can a SAP Build Action be setup to stream output to a SAP Joule Skill?

2026-02-06T12:17:28.108000+01:00

We have an API which streams the AI Reasoning output in real-time.

We can surface the streamed output at a command line by calling our API as follows:

try:

with requests.post(

API_URL,

json=payload,

headers=headers,

stream=True, # 👈 enables streaming

) as response:

Ideally, we'd like to present this streamed output in a SAP Joule Skill, with an action for our API. However, the output is not streamed, it returns only the final step of the output in one go, so not only is the full response not shown, it also takes longer to appear, which is not a good user experience.

Can Joule Skills/SAP Build Actions handle streamed output and how that acheived?

Business Partner creation $batch fails at “Call Web Service” in SAP Build Process Automation (BPA)

2026-02-10T09:41:50.923000+01:00

Hi everyone,

I am using SAP Build Process Automation (BPA) together with SAP S/4HANA Cloud, Public Edition to execute SAP’s standard template “Mass Create of Business Partners (58Z)”.
My goal is to create Business Partners via the API_BUSINESS_PARTNER OData service using a $batch POST request.

However, the automation fails at the Call Web Service step with the following error:

irpa_core.error.RequestError: Response code 401 (Unauthorized)

The earlier steps run successfully; the issue occurs only when BPA executes the actual $batch POST for Business Partner creation.

Environment

Target system: SAP S/4HANA Cloud Public Edition
Main automation tool: SAP Build Process Automation (BPA)
Scenario: Create Business Partners via API_BUSINESS_PARTNER $batch
Template: Mass Maintenance of Business Partners (58Z)

Current problem

BPA reaches the Call Web Service activity that performs:

POST https://<tenant>-api.s4hana.cloud.sap/sap/opu/odata/sap/API_BUSINESS_PARTNER/$batch

At this moment, BPA throws:
401 Unauthorized (irpa_core.error.RequestError)
Additional data I can provide (sanitized)
- Communication User / System / Arrangement screenshots
- BPA logs for HEAD and Call Web Service (request/response headers)
- If needed, I can test in Postman using the same Communication User and share:
  - GET A_BusinessPartner?$top=1
  - HEAD x-csrf-token: fetch
  - POST $batch
This may be a basic question, but any guidance or clarification would be greatly appreciated.

This may be a basic question, but any guidance or clarification would be greatly appreciated.
