- The SAP Business Framework is an integrated, open, component-based product architecture that encompasses SAP R/3 enterprise applications and third-party products and technologies. The advantages of SAP R/3 can be summarized as flexibility, scalability and expandability. SAP R/3 is often referred to in terms of “applications” or “modules”. A SAP R/3 application or module is a set of programs that has been designed for a specific type of business processing. Examples of SAP modules are FI (Financials) and SD (Sales & Distribution). Within the context of the Business Framework, these applications are referred to as “software components”. With each release of SAP, there is further de-coupling of the application modules to support SAP’s vision of developing R/3 into a family of components that can be upgraded individually.
- All R/3 systems include a set of core components, referred to as R/3 BASIS. Examples of SAP BASIS components are the ABAP Interpreter and the ABAP Dictionary. The R/3 BASIS system is what guarantees the integration between all of the application modules and also guarantees that the application modules are platform independent. A typical SAP R/3 installation must include BASIS and will also include one or more of the SAP modules.
- Customizing is the adaptation of the general SAP system to a company’s specific requirements. SAP is typically customized via the following two methods: Configuration ABAP development Configuration is the assigning of values to thousands of possible settings within the SAP modules. The following are examples of configuration activities: Specifying whether Purchase Order numbers will be user entered or system generated. If system-generated numbers are to be used, a number range must be set up as well. Specifying the required fields on a customer order screen. Specifying the fields that will comprise the code block for a particular type of journal entry. Setting up company codes and default currencies for each company. ABAP development encompasses the creation and modification of ABAP programs.
- ABAP is a programming language created by SAP for the development of application programs. SAP developers use ABAP to build the transactions that comprise SAP R/3 applications. SAP customers use ABAP to add additional business functionality (i.e., customize) the SAP R/3 applications.
- ABAP development activities typically fall into one of the following categories: Reports Interfaces Conversions Extensions Forms
- An ABAP report program reads data from the SAP database, performs any required data manipulation (e.g., summarization, sorting) and outputs the data to either the computer screen or a printed page. SAP provides many standard ABAP reports with the base R/3 installation. Most SAP customers, however, wish to have their own set of custom reports to complement the suite provided by SAP. These custom reports will be created by the ABAP development team as a part of the SAP implementation project. There are a number of other tools available to facilitate the development of reports using SAP data, including SAP ReportPainter, SAP Open Information Warehouse, SAP Business Warehouse as well as numerous third party reporting and data warehouse tools. Most SAP customers will use one or more of these other tools in addition to custom ABAP reports. An examination of these additional tools is not within the scope of this course.
- With the majority of SAP installations, the enterprise solution will comprise some other systems as well as SAP. Each of these other systems (i.e., tax system, production scheduler) must be able to communicate with SAP. This communication is performed via interfaces. Interfaces are typically categorized as inbound (i.e., SAP is the target system - the data is coming in to SAP from another system) or outbound (i.e., SAP is the source system - the data is taken out of SAP and sent out to another system). An interface typically has three program components: Extract Translation Load An extract program will execute on the source system, and a load program will execute on the target system. A translation program may be developed on either the source or target system; this is dependent on the design. The above examples show translation occurring in SAP. Interfaces can be developed to execute in one of the following three modes: Synchronous (i.e., online, real time) Asynchronous (i.e., near real time) Batch
- When SAP is implemented at a company, it is typically going to be replacing a number of existing systems (i.e., legacy systems). Before a legacy system can be “turned off,” key business data must be migrated from the legacy system to SAP. The process for moving the data is referred to as “conversion.” From a development perspective, conversion programs are designed and developed in the same manner as inbound interfaces. Examples of data that often needs to be converted are: General Ledger Account Balances Open Purchase Order and Inventory
- SAP provides a number of options for extending the base SAP software. Customizing: SAP provides a number of “hooks” (commonly referred to as user-exits) that allow for the tailoring of SAP functionality to meet a company’s specific business needs. This option is typically exercised when it is absolutely necessary to change SAP-delivered programs and an appropriate user-exit exists. Modifications: SAP permits SAP-delivered programs to be changed directly. These changes are typically not supported by SAP and must be reapplied following every software upgrade. This option is typically exercised as a last resort. New ABAP development: SAP allows the augmenting of the standard SAP R/3 through the development of additional objects and programs without changing existing SAP R/3 programs. This is the preferred process of adding new functionality to SAP in the absence of an applicable add-on/bolt-on. Add-on/Bolt-on: A number of third party products have been introduced in the marketplace to provide additional functionality to SAP. Many of these products are certified by SAP. These solutions are typically used when customer requirements are not fully satisfied by base SAP and a suitable product exists to fill the gap.
- An SAPscript form is an R/3 template that consists of layout and content information. A specific SAPscript form is assigned to each form (needed when dealing with your business partners). SAPscript forms are used by the R/3 system to print the forms, distribute them via several channels such as E-mail or fax, or display them on screen. Examples of SAPscript forms: Sales Order Confirmation Invoices Purchase Order Checks
