Hi Markus,

I'm not sure if I'm correct here, but I would like to know if BTP is ready for SAP Business One now? We are very unsure if we should get certified for BTP platform if it is not ready for SBO yet.

Can you help me with this problem?

With kind regards,

Benjamin

Hello Markus,

In the manual deployment step, where the "oauth-configuration" attribute is added on the XSUAA resource, it mentions we should add the approuter URL. This also stated in the SAP Note in case there is an error with the domain. However, the learning course does not explain where should we pick the approuter URL or if we should add ourselves based on the app name + domain name from the BTP region and account. 

Can you share what should be done in this part? 

Thank you

  @JTR refer the redirect URI

you can use wildcard in the URI: 

        oauth2-configuration:
          redirect-uris:
          - https://*.cfapps.us10-001.hana.ondemand.com/login/callback

@emmanuelt  Please make sure the subaccount has all the service and respective plan assigned in 'Entitlements':

for example: one of the error is for offering "hana" and plan "hdi-shared":

similarly for 'xsuaa' and plan "application":

Hi @VinayKumawat,

Your solution works. Thanks! 

However, I'm still getting another error: Error creating or updating application "risk-management": Controller operation failed: 422 Unprocessable Entity: CF-UnprocessableEntity(10008): Routes quota exceeded for organization 'xxxxxxxtrial_trial-us-xxxxxxxx'.

I checked my space and it says "100% of memory quota used". I Appreciate your help, thanks.Quota Plans.jpgdev space.jpg

@emmanuelt  for this this learning journey please check in global account and assign maximum units for cloud foundry to your subaccount:

VinayKumawat_0-1679410431983.png

then check your subaccount for the quota if it is assigned to your Cloud foundry space.

Hi @VinayKumawat

I was able to successfully deployed it now. Thanks for your help. Though, I still have one more problem after the deployment. I kept getting "Authorization Request Error. There was an error. The request for authorization was invalid" when trying to open the app.  error.jpg

Best Regards,

@emmanuelt I'm having the same problem after successful deployment. 

But there was one time i removed the app-router URL in the "redirect-uris" parameters and this problem disappeared. 

Then, i just experienced an error "Forbidden" when executing the get call to retrieve the info in the application but i interpreted as being connected to the roles as i haven't yet assigned to myself. 

Still need to figure out this part.

@VinayKumawat 

In regards to your comment, this is one of the questions i had and was confused. 

Documentation in Help SAP, aligned with your comment, indicates this property should be maintained on the xs-security.jon but the exercise steps indicate it should be added on the mta.yaml file. 

Can they be added on both? Should they be added on both? 

On an additional level, i understand the usage of wildcard but the exercise also states "-app-router" in the URI. Is this supposed to be the final URI that will be the application which is consumed by the user? And in SAP BTP DEV space will include another URL from the approuter which then redirects to the defined URI on oauth2 parameter? 

 

JTR_0-1679487272915.png

Anyway, i haven't done a new deployment the past days but it's working now fine for me. Even the odata calls to each service. 

Thank you @VinayKumawat

Hi @JTR, thank you for pointing it out. I have added the "redirect-uris" code in xs-security.json instead of mta.yaml file. Unfortunately, I'm getting "Not Found" page after I access the app.  I have already redeployed this. 

Hi @VinayKumawat, kindly advise. Thanks

@emmanuelt @JTR  please add into mta.yaml

VinayKumawat_0-1679494825509.png

you can construct this URL by looking at the API endpoint in subaccount:

VinayKumawat_1-1679495063285.png

it is https://api.cf.us10-001.hana.ondemand.com so rediect uri can be:

https://*.cfapps.us10-001.hana.ondemand.com/login/callback

for more details refer 2864831 - "The redirect_uri has an invalid domain" error when using a custom domain in Cloud Foundry...

Hi @VinayKumawat, I just want to clarify where we should really put the redirect uri. You instructs us to put it in mta.yaml file but the link you sent instructs us to put it in xs-security.js file.

Anyway, I have tried to put the redirect uri into three different scenarios

1. mta.yaml file only

2. xs-security.js only

3. Applied to both

I redeployed it each and every time and still getting an error. Not sure if I'm missing anything else. 

For your help. Thanks

Best Regards,

Emman

Hi all. I'm getting the same issue after making the redirect URI changes above. In my case, I'm using a Trial account. What else would I need to do if that's part of the issue? Thanks!

Using the following configuration in the mta.yaml has fixed my above problem:

        oauth2-configuration:
          # <-- add this
          redirect-uris:
UPDATE: since the above, - https://*dev-risk-management.cfapps.us10-001.hana.ondemand.com/login/callback now works too, so it must have been a glitch 🤔
The good news is that it works in the Trial account 😊

Sample certification questions

For SAP Certified Development Associate - SAP BTP Extension Developer, I've concerns with two of the four sample questions:

  1. What are some SAP recommendations for deploying large apps to Cloud Foundry?
    The answer isn't evident from the content.
  2. Which of the following dev space types does NOT contain MTA Tools by default?
    MTA Tools are now included by default in the Basic dev type (assuming it's referring to BAS).

Please can the sample questions be updated so they better reflect the content of the learning journey?

I await confirmation. Thanks!

Hi @Former Member, thanks for the update. Glad it works for you. Unfortunately for mine, I kept getting an "Not found" page when I open the URI. I tried to redo everything by deleting the entire space then recreate it again but I still keep getting the same error. I'm not sure if I'm the only one experiencing this.

Hi @VeeraSudheer ,

based on the screenshot you provided, I can see that you are entering an incomplete e-mail address. Please ensure to enter your full e-mail for logging into the Cloud Foundry environment.

Could you please also provide more insights into the errors you're facing during the SAP HANA DB creation?

Furthermore, I can also see, that you have tried to log in via SSO. The correct flag is "--sso" and not "-sso". 

I hope this helps.

Hello @markushaug ,

I am trying to follow the exercise from the very first unit of the learning journey. I am stuck in the unit Generating a User Interface. After generating the UI app, when I am launching /risks/webapp/index.html, the Fiori elements app is not opening. I am getting following error in console, which I am not able to rectify. Need your expert help on the same. I have just generated the UI app, have not added any code in the common.cds and annotations.cds file yet.

Hello Sap team,

I am stuck at this error of : The redirect_uri has an invalid domain...

I have this on my MTA.yaml file ->

   oauth2-configuration:
        redirect-uris:
 
Can you help please?
Just as a general remak, the first part of this learning Path is very well documented, all is epxlained , step by step, but the part 'Manual deployment', it is less documented, we don't understand why we do such action or add such config, also, the redirect_uri paragraph is not clear at all.
 
Thank you

I'd agree. This part of the training is temperamental. Sometimes it works; sometimes, it doesn't. Note my earlier comments above. Yes, please, more elaboration about the purpose behind the configuration would be helpful, hint, hint... Thanks!

Hello,

I'm encountering some issues when performing the exercise related to the CDS Restrictions and Roles. Here is the link for reference: https://learning.sap.com/learning-journey/build-side-by-side-extensions-on-sap-btp/defining-cds-rest...

When testing the project in the BAS local environment, I'm not getting the prompt that will allow me to enter a mock user and password. Here is the expected result:

mmarkvillanueva_0-1683604820166.png

As a result, I'm receiving the 401 Unauthorized error. Note that this is only happening in BAS. Once the CAP Project is deployed to BTP and the role collection is assigned to my User ID, I'm able to run the app successfully.

So it looks like an isolated case when performing some tests locally using mock user. Can you please advise how to address this? Thanks!

Hi @mmarkvillanueva,

sometimes it helps to close the browser and opening it again or opening the preview in incognito-mode of the browser.

If this does not help, could you please provide us with a Git-repository, so that we could have a quick look at it?

Hi @sdsanchez ,

let me provide you with the solution of this exercise, where you can copy and paste / compare the snippets:

https://github.com/SAP-samples/btp-side-by-side-extension-learning-journey/blob/solution/7_configure...

Please also double-check if you have the service correctly entitled in your subaccount. And please check if there is now a service called "risk-management-auth" in your subaccount with the state "failed". If so, please remove this one manually before proceeding.

 

BR,

Markus

Hello @markushaug, I Hope you are doing well. I am at the very end of the tutorial. I have finished the manual deployment as well.

Here is my Github Repo: https://github.com/Sudipta1452/RiskManagement.git 

However, facing these issues : 

Issue 01:  when I hit the risk-management application  URL  from the SAP BTP Cockpit,  the window looks like the following screenshot 

 

Step_01_Error.png

 

When I open the developer tools to inspect and refresh the URL, the application's index page gets loaded but with the following error that I can get from the console. The window looks like this :

 

Step_02_Error.png

 Issue02: API data is not getting fetched. which means No data is showing under the column Business partner.

Hi @Sudipta_1452 ,

thanks for reaching out to me!

I was able to solve the issue in your application regarding the Business Partner. However, I was not able to reproduce "issue 01".

Regarding Issue 02, allow me to provide a detailed explanation of the changes made:

Upon reviewing your package.json file, I noticed that you have specified the usage of SAP BTP destinations during production. However, in order to ensure smooth access to the business partner data once it is deployed to the Cloud Foundry runtime, I have identified two possible solutions:

1. Option one is to add the destination for the SAP Business Accelerator Hub (formerly SAP API Hub) to your SAP BTP subaccount. This will enable seamless interaction with the necessary APIs.

1. Alternatively, you can make the required modifications directly in the code as suggested in the pull request. These changes will ensure that the code aligns with the intended functionality.

Please review the pull request and assess which option suits your requirements best. If you have any questions or need further clarification, please do not hesitate to reach out to me. I am more than willing to assist you.

Best regards,
Markus

I had a hard time doing this learning journey as many steps were missing.

A lot of steps mentioned in answer section here should have been part of learning journey .

This will only discourage new learners from finding the otherwise good content.
