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

VinayKumawat

@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.jpg dev space.jpg

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

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

Regards,

Vinay

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.

Best Regards,

Emman

@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.

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?

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
