SAP ABAP Tutorial

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...
