Learn SAP OData Services Developments in 2 Hours

Explore the open data protocol OData, its use over the HTTP web, and how SAP NetWeaver Gateway enables client–server communication between SAP and non-SAP systems.

Learn about stateless architecture in SAP odata services and netweaver gateway. Each http request is independent, and the server forgets prior requests after the response.

Explore how rest defines representational state transfer as a resource-based architectural style behind Odata, and review the six constraints—client-server, stateless, cacheable, uniform interface, layered system, and code on demand.

Discover the advantages of Odata for developers, including XML or Json interfaces, self-describing messages, and the segregation of duties between back-end ABAP and front-end developers.

Explore why OData is the odbc of the web, acting as a middleware that provides database-like access by translating queries via a driver between applications and server resources.

Learn why SAP needed OData to replace point-to-point interfaces, reduce duplication and administration effort, and enable RESTful access, with OData standardized by Oasis.

Explore the SAP system demo introduction, as we traverse code to reveal entities, entity types, associations, and navigations, then demonstrate creating data in the system.

Demonstrate building an SAP odata service: define entity types and sets, regenerate runtime artifacts, customize get entity and get entity set, and register and activate the service for testing.

Create an SAP NetWeaver odata service project in SEGW, name and describe the project, assign a package, and initialize empty data models ready to define later.

Create entity types like bill header and bill item by importing structures, select fields and keys, then generate service methods: create, get entity, get entity set, update, delete.

Generate runtime artifacts for a data service by creating model and data provider classes and extensions, saving them to the transport, and finalizing step three of SAP OData service development.

Register and activate the OData service in the gateway system to connect the front-end Fiori system with the back-end SAP hub, and note the 501 not implemented error.

Implement the header entity set in the gateway, redefine get entity set and get entity in ABAP, and test data retrieval and Json output via the gateway client.

Test the header entity type and header entity set using the Uri, verify responses, and explore counting, multiple primary keys, and export to excel or json.

Implement and test the item entity type and its get entity set and get entity methods in the SAP OData service, then validate results in the frontend.

Learn to implement filter operations in SAP OData by building ABAP filters with select-options and range tables, and test runtime behavior using a debugger.

Learn how to pass multiple filters in a URI by applying the and conjunction, understand the syntax, and see how filters are implemented in the back end.

Learn to debug and analyze an SAP OData service using external debuggers, gateway client, and key/entity set concepts; test filters, keys, and entity navigation to verify data logic.

Learn how to implement the SAP OData POST operation by creating a bill info entity, configuring metadata, and testing payloads in the gateway service.

Explore how SAP Netweaver Gateway connects SAP to the outside world, creates and tests Odata services, and handles central hub and embedded system deployments through hands-on exercises.

Explore data query options like $select, $expand, and $orderby for SAP UI5 and Fury app data. Implement associations and navigations; perform CRUD operations and consume data from front-end apps.

We announce updated SAP OData course content in 2024, adding new topics and advanced material at no extra cost to enhance basics and complex integration projects.

Understand SAP gateway and the OData protocol to expose SAP data across web and mobile. Explore gateway deployment options central hub, embedded, and cloud provisioning, plus EDM and v2/v4.

Learn to build SAP OData services with gateway service builder. Define entity data model and generate runtime artifacts, register the service, and implement get calls for single or multiple records.

Learn to implement SAP OData services with get and post operations, generate runtime artifacts, and manage keys via IT key tab or IO tech request context.

Explore authentication options for SAP OData services and master query options—filtering, paging, sorting, select, and search—while learning OAuth scope management and safe gateway service deletion.

Learn how to handle SAP OData queries with single and multiple parameter filtering, date time filters, dollar options (filter, select, top, skip, count, inline count), sorting, paging, and performance tracing.

Explore association, navigation and cardinality in SAP OData services. Implement relationships between entities and use navigation properties and dollar expand to fetch related line items.

Explore $expand in SAP OData: compare framework expand with data provider expand, learn header and line item expansion, and the basics of create deep entity and deep insert.

Learn how to implement function imports in SAP odata, including post and get calls, service-level definitions, return types, and media handling with upload and access via byte streams.

Learn SAP OData batch processing with dollar batch, multipart batch requests, change sets, and E-tags, plus concurrency handling, and explore CDS-based OData services via the Saddle framework.

Discusses the SAP OData assignment, how the generated model derives from the entity data model via the model provider class, and examining service metadata.

Discusses implementing SAP OData with function modules, mapping a z table to a data source, and handling CRUD via one or more FMs with a constant indicator.

Explore common pitfalls in SAP OData filtering, including supplier name filters, URL encoding, and filter syntax. Compare basic filtering, paging, and sorting approaches discussed for assignment three.

Learn to build a SAP OData service with media-enabled entity sets, manage product image URLs, and create a REST API tested with Postman for online orders.
