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...

Module Objectives •Define debugging •Describe branching to debugging mode •Define key debugging concepts and functions •Explain the debugging mode •Describe examining/changing variables •Debugging in ADT •Identify breakpoints and watchpoints •Debug internal tables What is Debugging? •Tool used to identify and eliminate errors in ABAP programs •Allows the verification of program logic in a step-by-step manner by examining the results of individual statements Branching to Debugging Mode ABAP Debugging Key Debugging Concepts •Debugger modes •Examining the value of variables •Changing the value of variables •Setting breakpoints •Setting watchpoints •Viewing contents of internal tables Classic Debugging Display Below is the screen shot of how the debugger looks like. Classic Debugging Display Important Debugging Functions Single Step   -Processes the next program line Execute        -Allows the change of data contents during debugging Continue      -Pr...

SAP ERP ABAP 7.4 (Object oriented) DATA •Define variables with the DATA statement •Define constants •Apply type conversions •Explain arithmetic expressions •Perform date calculations •Use parameters (checkboxes and radio buttons) •Create selection screen boxes Predefined Data Types and Their Attributes Predefined Data Types and Their Attributes in SAP ABAP we have many type of data type to hold the value into the variables, from above table you can have a idea about the data type and meaning of datatype. Type-Specific Output below chart will give us the idea about type Specific output. Data Types in ABAP like other programming languages SAP ABAP have data types, which are divided into two categories, Elementary and structured, the Structured is further divided into Structure and internal table. Data Declaration - DATA Statement To store values in any variable we need to do the data declaration, we can only assign a value to a variable if the contain and value have the same datatype. R...
