The January 2024 release of the SAP Cloud Application Programming Model is out. The release notes in the CAP documentation cover everything you need to know. Here are some highlights from this release. There is a new CDS plugin that supports telemetry, including automatic open telemetry instrumentation. It's super simple to use. You should try it out today. You can now define an event as a projection on a remote entity, super useful when importing and integrating external services. There are improvements in the way large binary data is returned, which also is important in serving media data. CAP.Java now supports Cloud SDK version 5, and you should migrate as soon as possible. There are also features such as the ability to defer emitting events until you're ready, sorting improvements for lean drafts, and much more. Check out the release notes linked in the description for detailed information.

Also, there is a new website that helps us celebrate and explore the growing selections of packages for CAPnode.js. This is especially interesting in the context of the relatively new CDS plugin concept in concept and the growing availability of CAP Core and open source packages. Head over to bestofcapjs.org and check out what's hot, what's new, and even add your own package.

Hey, SAP developers. For those of you working in restful application programming model or in common term RAP, Let me share your hidden treasure that can come in handy. ABAP keyword documentation provides a list of all available language elements of the RAP behavioral definition language and their release dates. This allows you to easily look up for the features of each RAP viewer implementation type and find out whether they're available in your current product release. The table cover the full scope of the RAP BDL, including all statements for managed or unmanaged RAP views, BO interfaces, service projections, BDEV extensions, and even abstract behavior definitions. Andrea's blog post provides the link to the table in about keyword documentation seems like a helpful guide. Kindly check it out.

Hello, everyone. We are thrilled to announce that the monthly developer challenge is back. As many of you are aware, developer challenges are short, engaging, beginner-level puzzles designed to encourage you to explore and acquire knowledge on your topics. The focus for February 2024 challenge will be SAP Cloud Application Programming Model, CAP, and its plugins. CAP plugins are extensions to the CAP framework that enable developers to enhance the capabilities of their CAP-based applications. You can embark on this journey along with us every Wednesday for the next four weeks and build a simple CAP application and integrate a new plugin into this application every week. To join the challenge, simply post a screenshot of your solution as a reply to the discussion in this link. We look forward to seeing your innovative approaches and solutions. Good luck.

Hello, everybody. Hope you're all doing great. I would like to highlight the two key features in the latest release of SAP Build apps. We are all aware of the visual cloud function capability using which we can visually design and deploy application backend for the front end created using SAP build apps. It's a very powerful capability enabling the full stack development. Coming to the feature updates, number one, SAP has now added role-based user authorization to these visual cloud function projects to enhance the governance capabilities. A system administrator or a developer can create user roles and assign specific permissions to make the applications more secure. Number two, for the application front end that is built using SAP Build apps, if it is linked to a back end project that is created using visual cloud function, now there is a simplified method to embed this complete stack into the SAP Build work zone. To get started with this feature, identity authentication service tenant can be enabled in SAP Build work zone. If you would like to learn more about these updates, please check out the blog post by our product expert Esmee Xavior explaining these features and their enablement approach. Link to the blog post is in the description below. Thank you.

@TammyPowlas - Yes if you try to use that html snippet directly in the forum content - it will just display the text. But if you place it into the Signature setting in your profile, the Community Platform will automatically place it for you into any Q&A/Discussion posting you make. It is not used in comments on Blog Posts (such as here).

Also if someone doesn't want to see other people's signatures (not sure why that would be the case 😀 ), there is a setting in your profile in the Community where you can also disable the display of any users signature.

It's great to see you again if even virtually. Now maybe that you are back in the SAP space again, we'll bump into each other at an event in St. Louis.

Re: New SAP Community - Profile Signatures

2024-02-09T15:24:44.728000+01:00

@JimSpath - I believe the Community Platform follows this pattern in regards to signatures. It does not display them on comments on blog posts. But it does display them when you are posting in Discussions/Q&A. There is also the personalization setting that I showed earlier where you can disable to the display of all signatures from all people.

That's fine if you want to use an existing project but you might find it more difficult in later weeks in the challenge. We will ask you to use the plugins in specific ways - like adding logic to an exit handler that already exists as part of the sample application.

Re: February Developer Challenge - CAP Plugins: Week 1

2024-02-10T14:34:34.801000+01:00

Looks to me like you have an older version of CAP most likely. You want to be on version 7.x at least. I tested the challenge using 7.6.x. You can do a cds version to find out what you are running. Here's my cds version:

@Lakshmipathi - I don't know of any way to alter the badges displayed within the Community Profile. I believe it always displays your five most recently earned badges. But that's part of the reason I built into the badge signature the option to choose your badges.

February Developer Challenge - CAP Plugins: Week 2

2024-02-14T13:57:15.041000+01:00

If you missed week 1, you can find all the details: here

This week's challenge is going to build upon what we learned last week with the OData V2 plugin. We will continue working with the same project, but now we want to add support for GraphQL.

What is GraphQL?

GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data. Unlike REST, which uses multiple URLs to access different resources, GraphQL accesses all the resources from a single endpoint with queries that articulate exactly what data is needed.

GraphQL and OData are both specifications for building and consuming APIs but take different approaches to some aspects.

GraphQL is a query language for APIs and a runtime for executing those queries by using a type system you define for your data.

OData defines a set of best practices for building and consuming RESTful APIs. It extends REST by providing a uniform way to describe both the data and the data model, enabling more detailed queries and interactions with the data.

How does this impact the SAP Cloud Application Programming Model?

The SAP Cloud Application Programming model was designed to be protocol agnostic as much as possible. While OData V4 is the default service type exposed by CAP applications; CAP was never intended to only support OData or just one version of that specification. Therefore its possible from a single model and service definition to support both OData and GraphQL even with the differences in approaches used by the two different protocols!

Your Task this week

Use the GraphQl Adapter plug-in to add GraphQL support to your project and to ONLY the CatalogService endpoint. And make sure that this same service also still supports OData V4 in parallel.

GraphQL Adapter: The GraphQL Adapter is a protocol adapter that generically generates a GraphQL schema for the models of an application and serves an endpoint that allows you to query your services using the GraphQL query language.

https://github.com/cap-js/graphql

To complete the challenge, post a screenshot from the graphql test tool (which can be accessed from /graphql url of your application) running a query against the ListOfBooks entity in the CatalogService.

Bonus 1: The test tool doesn't automatically include a link to the GraphQL test tool. But using a server.js file we can use the on serving event to extend the CAP test tool ourselves. Your bonus challenge is to add the code to your project to expose a link in the test tool to the GraphQL page but only for the service endpoints that support GraphQL. Hint: Several of the samples in the SAP-Samples repository on GitHub perform this technique.

I can't commit immediately to doing a second CodeJam on a different date in the same location. I have to try to balance a set budget with many requests coming in from all over. I can put the request in the backlog and we can if perhaps we could slot it in for the 1/2 half of the year depending upon how budgets and other events plan out.

Proxy rewrite rule? Are you trying to change the main ODataV4 URL path? If so you can do that via annotation in the service definition now since CAP 7.0. June 2023 | CAPire (cloud.sap)

Just the RSVP is enough. You are of course welcome to travel in for the event if you want, but I think you will find most of the attendees are local to the area.

February Developer Challenge - CAP Plugins: Week 3

If you missed week 1, you could find all the details: here
If you missed week 2, you could find all the details: here

For this week's challenge we are going to mix things up. Week 1 and week 2 both focused on extending the protocol or version of service endpoints. This week we will use a plugin that has a completely different purpose. We are going use the Change Tracking plugin. This plugin both extends the data model and the Fiori UI automatically. It stores change history information, exposes it within our service and adds a Change History UI element to our Fiori application; all with extremely minimal effort on your part!

Your Task this week

The Change Tracking plugin provides out-of-the box support for automated capturing, storing, and viewing of the change records of modeled entities. All we need is to add @changelog annotations to your models to indicate which entities and elements should be change-tracked.

https://github.com/cap-js/change-tracking

Your task is to add change tracking to the Books entity and the Title attribute in your application.

To complete the challenge, post a screenshot of the Fiori UI for managing Books with the Change History with a change entry displayed.

Bonus 1: Add change tracking to the Books.Author association. However, don't display the unique ID when the association is changed. Instead, the change log should record and display the Author Name.

I actually did it in the same file. While I follow the concept of the separation of concerns, I don't do it as strictly has some do. I don't immediately put all annotations in a separate file. If the annotation impacts the data model; I actually like it to be as close to the data model definition as possible. Now, clearly UI annotations I always separate out.

With one exception; the annotation for value help. I feel like those belong in the data model although they certainly impact the UI. It's also about reuse and inheritance. Putting annotations like the value help into the data model ensures that they are available even if there are multiple different UIs built via annotations on that same model. This also might be my ABAP background where value help definitions are data dictionary objects and often tied in via the database table or structure.

I did have to stop and think about this particular annotation because it impacts both data model and UI. But ultimately, I thought in the future I'd more likely want to see which fields are marked for change tracking when I'm working with the data model itself.

I love the flexibility that CAP provides to allow for these different use cases and how one development group or company might adjust their own rules for what works best for them.

On a side note, this approach with separate files for annotations isn't just about separation of concerns of different layers but can also support reuse (as mentioned) and target platform specific logic. For instance, when you need HANA specific features you can have build rules that include only certain folders. But perhaps that's a topic for another day or another challenge.
