Deploy Java App on Kyma Runtime

2024-05-23T11:15:43.324000+02:00

Hi colleagues,

I'm following followed the steps described in the tutorial: #https://developers.sap.com/tutorials/deploy-nodejs-application-kyma.html

The only difference is that I use my own Java Web App (Based on Spring). I successfully deployed my app and the pod is green. The problem is that when I try to access it (as described on step 9) I get the error:

upstream connect error or disconnect/reset before headers. retried and the latest reset reason: connection timeout

when I connect to the k8s pod and use curl from there it works:

root@kyma-web-ocr-7bfd6bd995-g7tl4:/app# curl localhost:8080/health/isalive
Web OCR is alive. The pulse is 71root@kyma-web-ocr-7bfd6bd995-g7tl4:/app#

I'm attaching my deployment

SAP Experts,
Does SAP HANA Native application type of Dev Space inside SAP Business Application Studio supports SAP Continuous Integration and Delivery integration to transport objects across different spaces?Because most of the blogs that I visited says that CAP based project is the pre-requisite.

Thanks in advance!

CORS blocking access

2024-06-05T11:09:35.453000+02:00

Hi everyone,

I'm facing an issue with CORS blocking access in my application, below is what I've done in my frontend and backend applications.

In the frontend app I'm using angular to make this login request

const headers = new HttpHeaders({
      'Authorization': 'Basic ' + btoa(${this.clientID}:${this.clientSecret}),
      'Content-Type': 'application/x-www-form-urlencoded',
      'Access-Control-Allow-Origin': '*'
    });                                                                                                                return this.http
      .post<AuthResponseBackend>(
        'https://cors-anywhere.herokuapp.com/https://amwftwpkt.trial-accounts.ondemand.com/oauth2/token',
        data.toString(), { headers }
      )

it works only if I add this CORS link https://cors-anywhere.herokuapp.com/ before login link and open that link in my browser https://cors-anywhere.herokuapp.com/corsdemo to request temporary access to the demo server. I need it to work without these CORS links.

In the backend application, I'm working with spring boot and using security configuration. I've added allow CORS configuration in my security configuration as shown in my code snippets below and also above each controller I've added the CrossOrigin annotation. When I deploy my application on kyma and the frontend side tries to connect to it, It still gives an error due to CORS. Any help is appreciated.

Here are the github links for the full codes of the applications; Frontend application , Backend application

Thanks in advance.

Problem registering my desktop agent in my BTP Build Process Automation Trial Account

2024-06-19T09:29:23.588000+02:00

Hi everyone,

I'm facing an issue while registering my Desktop agent in my BTP Trial Build Process Automation App.

I followed the SAP Developers Guide to set up the agent locally on my PC, and I enabled the Chrome and Edge extensions to try and connect the agent with my trial app. However, I encounter a problem when clicking on the agent in the control tower to get the information needed to register it with my local desktop agent.

It loads for hours without any response. I thought it might be due to my internet connection, but nothing changed after switching to another Wi-Fi network.

Can you please help me set this up?

Thanks,
Ilyass

Monitor credit consumption to prevent over usage

2024-06-26T15:46:55.036000+02:00

SAP BTP Credits

Early Warning

Introduction:

Many BTP customers have negotiated contracts with SAP for their BTP credits. To prevent credit overconsumption, an usage predictor can be very helpful. Therefore, we propose implementing a detailed tracker with a usage prediction feature.

Usage Prediction Model:

Since business operations are often cyclical, we base our predictions on the usage from the previous two months. This approach could also account for seasonal variations.

Steps to Implement the Tracker:

1. Data Retrieval:

We will use the Usage Data Management Service API to gather consumption data for each global account and its associated subaccounts.

2. Data Processing:

The daily usage data for each subaccount will be classified and filtered to retain only the data from the last two months.

We will then compute the sliding means for each subaccount. This involves averaging the daily usage over the past two months.

3. Prediction Calculation:

The computed sliding means will be multiplied by the number of days remaining in the current month to predict future usage.

This prediction accounts for seasonality, providing a more accurate forecast shifted by two months..

4. Alert System:

Based on the predictions, an alert will be sent to the account owner if they are likely to over consume their credits. The alert will provide a detailed view of the credit usage with charts and tables associated with a prevention message like ‘We recommend you to review your credit consumption or contact SAP for a renewal of your contract’. This allows them to take preventative action or renegotiate their credit contract with SAP.

Technical Implementation:

We will deploy a Python-based microservice on SAP BTP Cloud Foundry.
This microservice will:

Scrape usage data via the API endpoint.
Generate time series for analysis.
Present the data in an easy to understand chart format.
Provide recommendations based on the usage predictions.

Conclusion:

This usage tracker will help BTP customers manage their credit consumption more effectively, avoiding overconsumption and potential cost overruns.

Title: Issue with Table Sequencing When Transitioning from "In Scope" to "Supported Features" in SAP

2024-07-04T13:31:13.068000+02:00

Title: Issue with Table Sequencing When Transitioning from "In Scope" to "Supported Features" in SAP

Description:

Hello,

In our SAP system, we have been using the "In Scope" version, and the sequence of our tables was as follows:

Initial load of products
Basic data
Plant data
MRP area
Storage location
Valuation data
Distribution chain data
Description data
Units of measure data
Tax classifications
Production resources tools
Inspection setup data
Warehouse number data
Storage type data
Data transfer for forecast values
Data for quality management
Additional EANs

However, we are now required by SAP to use the "Supported Features" version, and the sequence of tables in this system has changed to:

Basic data
Additional descriptions
Alternative unit of measure
Additional GTINs
Distribution chains
Tax classification
Plant data
Forecasting data
Storage locations
Production resources tools
Inspection setup data
MRP area
Warehouse number data
Storage type data
Valuation data
Valuation current period
Valuation future prices
Internal number range

This new sequence is causing issues in our current business processes and data flow. How can we ensure that our data is processed in the same sequence as in the old version ("In Scope") while using the new system?

We tried using LTMOM (Landscape Transformation Mapping and Object Modeling) to revert the table sequence to the old version, but we couldn't fully understand how to do it.

Question:

How can we use the LTMOM tool in SAP to restore the table sequence from the old version ("In Scope") to the new system ("Supported Features")? Could you provide detailed steps and examples?

Thank you.

Error: Authentication kind "jwt" configured, but no XSUAA instance bound to application

2024-07-09T10:39:07.092000+02:00

Hello community,

I would like to connect CAP Node.js app to external SAP service in production env using destinations. It is important to use OAuth2.0ClientCredentials authentication method. Sandbox works for me. Official document is bit confusing.

When I run production profile, I am getting below error. Do I need any additional NPM package, or require additional configuration in package.json or elsewhere?

What to do in order to successfully fetch data from "production" environment? Thank you.

Recording negative volumes for positive dollar amounts

2024-07-18T00:16:40.136000+02:00

Hello all,

We are trying to interface one system with S4 Hana, and one of the GL entries required to be posted is positive purchases with negative dollar amounts to the same GL account, how do we incorporate that?

Do you suggest any kind of rule needs to be introduced in the interface for reading the data or do you think that separate STAT account should be created? Your wisdom and response is valued and appreciated.

Thanks,

SAP Kyma environment ready for Production?

2024-07-24T16:58:15.117000+02:00

I have recently been exploring the SAP Kyma environment using a Trial BTP account.

Full disclosure, I am an old BASIS hand and not familiar with Kubernetes.

Going through the Developer Central Tutorial "Deploy a Node.js Application in the Kyma Runtime" I was able to get everything done, except getting the application to respond from the Internet. I also explored the Remote Work Processor from SAP Automation Pilot to a Kyma cluster.

My experience has not been good.

For the RWP I was eventually able to get it to deploy and run once I read through the GO code to see that the Environment variable names had changed. Contacting the developer I got "this is beta and the Automation Pilot code has not caught up to the RWP code."

For the simple Node.js exercise I have built and tried 3 different Kyma clusters in two different regions (AWS US and Azure Singapore, the two the Trial accounts work in) and as far as I can tell everything is deployed correctly. I have read several blogs and trouble shooting pages, the 503 error points to maybe a Certificate issue, but the logs from the POD don't back this up.

Anyway, the main reason for this post is to ask if anyone is actually running Kyma in Production? When something as simple as the Tutorials don't work it doesn't give me a lot of confidence. The Cloud Foundry tutorials had minor issues with Node.js package versions, but was easy enough for me to figure out and make work. Is the Cloud Foundry Environment and of course the Build series of apps what SAP would prefer to have used, and Kyma should be seen as perpetual Beta?

At this point if a client asked if they should use Kyma, I would say no.

Porting Apps to SAP BTP

2024-07-25T06:40:29.722000+02:00

Hi everyone! im new to SAP BTP so i want to ask some question. so I have this current setup on my application:

- the web framework is written using python programming language and flask
- parallel processing is written using python and celery
- the task queue I used is redis
- deployment is handled by kubernetes
- database is Postgres with PG-Bouncer for managing the connection

So I need to move those component to the SAP BTP, but I don't have enough resource to do that, can you please give me advice or reference doccument how to do that, what I'm already try is deploying native python program to BTP using the cloud foundry and connect it to HANA DB.

And my boss said that it is possible to develop the apps inside the BTP, so he said I just need to port the current apps into BTP using python and postgres and all other things like the parallel processing, deployment, security will be handled by the SAP BTP (so I don't need K8S, Redis, Celery). is it possible to do that? Thankss!

Use ServiceBinding data for APIRule jwt accessStrategies configuration

2024-07-29T22:21:35.006000+02:00

Hello Kyma Experts,

when using the helm charts generated by CAP there is a ServiceBinding to XSUAA which is used via a

volume mount of the service binding secretName. I would like to use this secrets also in the APIRule for a jwt accessStrategies configuration. In https://github.com/gregorwolf/cap-azure-ad-b2c/blob/main/kyma/deployment.yaml#L49 I did this manually with a static configuration of the trusted_issuers and jwks_urls. But I want to get the configuration be flexible so I do not need to adjust it between dev / qa and production.

How to call Webservice using Javascript of AppGiver (without destination)?

2024-08-04T03:23:45.643000+02:00

Hi Friends,

Currently I have a OData Service which is working fine in Postman when tested. Also I am able to call this service directly in Business Process Automation using JavaScript step without any destination.

The input payload for execution is:

Payload Info:

var url = "https://jsonplaceholder.typicode.com/posts/1" // a sample url 
{ method: 'GET', 
  url: url, 
  headers: { 'Content-Type': 'application/json'}
}

And this work good & perfectly also.

Now I would like to call the same service using BTP Build App using JavaScript step. I tried many ways. But unlucky.

Can any one help me on this for the payload given able please?
