Where ABAP meets SAP HANAABAP lays the foundation for countless SAP applications, with a broad range of features and functionality for creating powerful business solutions. SAP HANA provides the opportunity to innovate with new and sophisticated technologies. If you do SAP software development you may have heard of Git, GitHub, or similar products such as Mercurial, Subversion. The demo will go through the steps to install the SAP HANA Studio, the ABAP Development Tools (ADT), and the BW Model Tools (BW-MT). See how SAP HANA has changed ABAP! Whether you re studying for certification or just want to see what's new, you can learn to design simple and advanced SAP HANA. With support package stack (SPS) 0. SAP Net. Weaver 7. SAP has brought ABAP and SAP HANA together with features that enable developers to leverage the best of both worlds, not only in new custom development projects, but also in their existing applications. Delivered as a globally available service release in December 2. SPS 0. 5 offers many new artifacts that ABAP developers can use to push down code to SAP HANA and bring innovation to their applications at various levels of abstraction. This article explores in detail the major ABAP development features delivered with SPS 0. SAP HANA — in particular, it looks at new features for database- independent programming with Open SQL, unified data modeling and definition with core data services, and simplified control of stored procedures with ABAP- managed database procedures. It also provides a brief look at some of the features available with the next major functional support package stack for SAP Net. Weaver 7. 4, SPS 0. Q3 2. 01. 4. All the features discussed can be easily explored using the Eclipse- based ABAP development tools for SAP Net. Weaver (known as ABAP in Eclipse), which provide many productivity features that can help developers in their daily development work. Database- Independent Programming with Open SQLIn ABAP- based environments, Open SQL has provided the proper level of abstraction for database processing for many years, enabling ABAP programs to perform operations on any SAP- supported database. The main advantages of Open SQL are its database- platform- independence; its integration into the ABAP language and runtime environment by means of internal tables; and strong support of SAP Net. Weaver Application Server (SAP Net. Weaver AS) ABAP with table buffering, SQL statement caching, and cursor caching. Many tools are available, such as the ABAP source editor and the SQL trace tool (transaction ST0. SAP HANA SQLScript Basics, Debugging, and ABAP Connectivity Rich Heilman, SAP HANA Product Management, SAP Labs, LLC.Open SQL programming during application design mode and to monitor and trace SQL execution during execution mode. Open SQL provides an optimal means for ABAP developers to abstract from the characteristics of the underlying database — in fact, developers are often never even aware of which database platform is actually used underneath. While this provides a thorough foundation for SAP Business Suite, the traditional programming style used by developers includes certain behaviors that become challenging when it comes to big data and the vast amount of complex information that needs to be processed. Many traditional ABAP programmers use a programming style that centers on the application server. Specifically, they often use large nested SELECT loops that are often quite natural for processing large data sets, but essentially copy all relevant data to the application server, where the data is managed in ABAP internal tables. When the processing is done and changes are made, the internal tables are written back to the database. There are many existing custom reports in customer landscapes that use a similar execution scheme, both in dialog and batch processing. ABAP lays the foundation for countless SAP applications, and SAP HANA provides the opportunity to innovate with new and sophisticated technologies. The Influence of SAP HANASPS 0. SAP Net. Weaver 7. May 2. 01. 3, provided customers with the option to use SAP HANA as the database for SAP ERP, SAP Customer Relationship Management (SAP CRM), and SAP Supply Chain Management (SAP SCM). Developers were able to use SAP HANA- specific artifacts, such as analytical views and calculation views, in their ABAP programs — both new and existing, with some reengineering in the existing programs to ensure that logic executes where it semantically belongs — to accelerate data processing dramatically. In- memory technology powered by SAP HANA allows developers to delegate processing that is data- intensive to the database layer, rather than managing everything in the ABAP server and transferring huge amounts of data between the server and the database. This paradigm shift to “pushing down” data- intensive code enables more efficient execution and performance, as well as a separation between front- end UI logic and back- end application and database logic to support a modern application architecture. With major SAP solutions such as SAP Business Warehouse (SAP BW) and SAP Business Suite now optimized for SAP HANA in addition to fully supporting traditional database platforms, developers needed a new approach that combines the processing power of SAP HANA with a semantic layer in ABAP that is not bound to a particular platform. To meet this need, the ABAP language team at SAP completely renovated the Open SQL architecture to provide a new Open SQL syntax that seamlessly integrates into the ABAP environment, like the traditional Open SQL, but provides enough hints to the underlying database layers for optimal execution. The New Open SQLSPS 0. SAP Net. Weaver 7. Open SQL, which includes support for comma separated lists, enhanced string expressions, the definition of host variables in a more standard fashion, and fewer restrictions for joins. Figure 1 shows a listing, based on the well- known open invoice items example scenario, of modern Open SQL code in ABAP that showcases the philosophy of the new and extended Open SQL syntax provided with SPS 0. SPS 0. 8. In the TYPES section, a demo structure is defined as a concatenation of a sales order, a business partner, and an invoice header to keep results from a multiple join operation. This join is expressed in the SELECT statement, where the corresponding three tables (snwd. The ~ selector is used to refer to a particular column, such as so~buyer. SPS 0. 8 adds the ability to refer to all columns of a row with, for instance, so~*. The host variable (in this case, the internal table) where the result set is stored is prefixed with @ (@lt. The new syntax is syntactically closer to the SQL- 9. Open SQL, which enables greater execution efficiency. It also serves as an important basis for the definition of core data services views, which is a SQL- based data modeling and definition feature included with SPS 0. Moving away from the traditional loop processing with SELECT . It also includes consumption of parameterized core data services views, which we’ll look at in more detail next. Unified Data Modeling and Definition with Core Data Services. In the past, data modeling in ABAP usually involved defining and managing views of your data on the ABAP server, using tools such as the ABAP dictionary in the ABAP Workbench. In keeping with the paradigm shift of moving data operations to the database — to take advantage of in- memory processing, for instance — SAP introduced core data services (CDS) with SPS 0. SAP Net. Weaver 7. CDS is a data modeling infrastructure for defining and consuming semantic and reusable data models on the database, rather than on the ABAP server, regardless of the database system used. CDS offers a SQL- oriented abstraction layer that extends the SQL- 9. OLTP and OLAP models of data definition, data query, and data manipulation. Supported natively in both ABAP and SAP HANA, the data models are expressed in data definition language (DDL) and are defined as CDS views, which can be used in ABAP programs via Open SQL statements to enable access to the database. CDS provides a range of advantages for ABAP developers, including: Semantically rich data models. CDS builds on the well- known entity relationship model and is declarative in nature, very close to conceptual thinking. Compatibility across any database platform. CDS is generated into managed Open SQL views and is natively integrated into the SAP HANA layer. CDS offers a variety of highly efficient built- in functions — such as SQL operators, aggregations, and expressions — for creating views. Support for annotations. The CDS syntax supports domain- specific annotations that can be easily evaluated by other components, such as the UI, analytics, and OData services. Support for conceptual associations. CDS helps you define associations that serve as relationships between different views. Path expressions can be used to navigate along relations. Customers can extend SAP- defined CDS views with fields that can be automatically added to the CDS view. Defining a CDS View. CDS views are defined using the CDS editor in ABAP in Eclipse. Figure 2 shows the definition of a DDL source file for a CDS view (zcdsv. The view contains two fields: one containing the key of the buyer, and another containing the classification of the buyer, which is determined based on the number of open invoices of that particular customer. The classification is obtained with the SQL operators group by and having count (distinct), which segment the buyers into three categories: less than or equal to 2,0. The complete CDS view is the union of these three different categories expressed with the SQL operator union all. The addition all does not eliminate potential duplicates, to avoid any additional processing time that would degrade performance, but in this case the categories are disjointed by definition, so they will have no records in common. Without any procedural logic in ABAP, we have defined a CDS view. Figure 3 shows how easy it is to combine the results of the classification view with some more readable fields from the business partner master table, for instance, such as the customer number and customer address. This is achieved by a JOIN operation of the table snwd. The CDS editor offers semantically rich code completion and field completion capabilities by pressing Ctrl+Space, which launches the pop- up in Figure 3 that displays the fields that can be chosen from the business partner master table. Figure 3 — Adding fields to the example CDS view.
