SAP ABAP Tutorial

PDF-based print forms are a part of the Interactive Forms based on Adobe software package solution and are used for mass printing in SAP systems. as well as normal output on printers, and also the choice of archiving documents, you'll be able to additionally use your application to send a PDF to the Business Communication Services (BCS). Here, you've got the choice of faxing or e-mailing your documents. The following provides you a summary of how a PDF-based print kind is structured and additionally tells you the way to create a PDF-based print from within the development setting of the ABAP work bench. The integrated Adobe LiveCycle Designer software system supports you after you do that. This software system should be put in on your forepart before you'll be able to produce a layout. to visualize a print preview of your kind, you initially got to install Adobe Reader or an entire version of Adobe athlete. This documentation doesn't discuss however documents are wri...

Web Dynpro is SAP’s standard UI technology for developing business applications with Web-based user interfaces.the web Dynpro is consists of a runtime environment and graphical development environment and tools that are integrated into the ABAP workbench.SAP Web Dynpro is based on original MVC design for decoupling presentation and application logic.Windows, Views, UI elements, Layouts, and Controllers form the basic components of a Web Dynpro application.Data binding is the means by which data is automatically transported from a view controller’s context to a UI element in its layout.Specific iViews should be created in order to run a Web Dynpro ABAP application within SAP enterprise portal.All WDA components, applications, and parts of the component are integrated parts of the standard correction and transport system (CTS).The standard ABAP lifecycle concepts fully apply to all Web Dynpro-based applications. Objectives goals: Explain the significance of Web Dynpro along with the We...

ABAP AUTHORIZATION CONCEPT Describe SAP Authorization Concept Adding authorization checks to programs using AUTHORITYCHECK statement Authorization Concept  The SAP authorization concept was developed to protect transactions, programs, and services in SAP systems from unauthorized access. The administrator (usually from BASIS) assigns authorizations to users that determine which actions (transactions/programs) a user can execute in the SAP system. The authorizations represent instances of generic authorization objects and are defined by the activity and responsibilities of the employee. Adding Authorization Checks to Programs It is almost always a good practice to add authority checks to your custom developed programs. To add authorization checks to programs, you need to do the following:  Determine the Authorization Field/s  Determine the Authorization Object/s  Add Authorization Checks in your program Use the ABAP AUTHORITY-CHECK statement. Specify alphabetic values...

Module Objectives Purpose of ABAP Unit Creating Unit Tests Fixture Methods ABAP Unit Test Class Wizard ABAP Unit Test Classes in ADT Purpose of ABAP Unit ABAP Unit is part of the test landscape for ABAP programs. ABAP Unit lets you implement unit tests. ABAP unit tests are methods of specially designated ABAP classes. Test methods work as scripts, with which code under test can be run, and with which the results of a test can be evaluated. ABAP unit lets you test the code at unit level, independent of the entire solution. Creating Unit Tests ABAP unit tests are implemented in the form of test methods in local test classes in any ABAP programs. The expected results are checked with static methods of help class CL_ABAP_UNIT_ASSERT or CL_AUNIT_ASSERT . Unit test Test Properties Risk Level Harmless – the test does not affect any existing processes and/or Database data. Dangerous– the test will change Database or Persistent Data Critical – the test will affect customizing data Duration Sh...

OOP Understand the details of object-oriented syntax elements in ABAP Objects and use these effectively Create object-oriented models of business applications Use the tools in the ADT 2.70 to develop object-oriented applications what problems we were having in Procedural programming. Long code due to variable declaration Extensive processing after SQL statement Multiple Commands to perform simple operations Code reusability and Maintenance SAP’s solution In-line declaration SQL Expressions ABAP Expressions OOP Advantages of OOP over Procedural programming Improved software structure and consistency in the development process Reduced maintenance efforts and less susceptibility to errors Better integration of the customer/user into the analysis, design, and maintenance process Easier and safer possibilities for extending the software OOP in ABAP Essentially the same as those of other modern object-oriented languages like C++ or Java Some elements present in ABAP objects are not offered i...

BASIC ALV •Define and describe ALV •Discuss and use the standard function module ‘REUSE_ALV_GRID_DISPLAY’ in ABAP program •ALV Navigation Define and Describe ALV The ALV (ABAP List Viewer) is a flexible tool for displaying lists in SAP. The tool provides common list operations as generic functions and can be enhanced by user-defined options. This allows you to use the ALV grid control in a wide range of application programs. For this module, the simplest way to use ALV will be discussed. Advanced topics in ALV may be discussed in the later part of the Training. Sample ALV Output Sample ALV output The ALV Field Catalog The field catalog is an internal table which contains information about the fields to be displayed on the ALV. The type is SLIS_T_FIELDCAT_ALV. We must first build the field catalog before displaying any output in the ALV. There are many fields in the field catalog but for a simple output, the only necessary fields are FIELDNAME and SELTEXT_L. Using the FM ‘REUSE_ALV_GRID...
