There are two Types of Debugging are available: Classic Debugger New Debugger The Classic ABAP Debugger   displayed in the same window as the application which also has some restrictions. Some ABAP programs (such as conversion exist) cannot be analyzed in debug mode for technical reasons.  Classic Debugger Functions: Breakpoints Static Breakpoints Dynamic Breakpoints Breakpoints at Statements Breakpoints at Subroutines Breakpoints at Function Module Calls Breakpoints at Methods Breakpoints at System Exceptions Saving Breakpoints Managing Dynamic Breakpoints Watchpoints If you want to interrupt a program when the contents of a field or structure change, use a watchpoint.  You can set up to ...

NATIVE SQL  and OPEN SQL in SAP ABAP Open SQL allows you to access the database tables declared in the ABAP dictionary regardless of the database platform that the R/3 system is using. Native SQL allows you to use database-specific SQL statements in an ABAP/4 program. This means that you can use database tables that are not administered by ABAP dictionary, and therefore integrate data that is not part of the R/3 system. Basic Open SQL Commands SELECT INSERT UPDATE MODIFY DELETE OPEN CURSOR, FETCH, CLOSE CURSOR Native SQL As already mentioned, Native SQL allows you to use database-specific SQL statements in an ABAP program. To use Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement. Syntax EXEC SQL [PERFORMING <form>].   <Native SQL statement> ENDEXEC. ABAP Syntax The syntax of the ABAP programming language consists of ABAP statements and comments. ABAP Statements Normally, each ABAP ...

Modularization in ABAP When you modularize source code, you place a sequence of ABAP statements in a module. Then, instead of placing all of the statements in your main program, you just call the module.When the program is generated, the source code in the modularization unit is treated as though it were actually physically present in the main program. SAP- ABAP Macro Include Programs Subroutines Function Modules Function Groups SAP- ABAP Macro If you want to reuse the same set of statements more than once in a program, you can include them in a macro. You can only use a macro within the program in which it is defined, and it can only be called in lines of the program following its definition. Macros  can be useful for long calculations or complex WRITE statements. Syntax DEFINE <macro_name> 'Macro Statements END-OF-DEFINITION Macros can use Parameters &N where N = 1,2,3... Example:- DATA: number1 TYPE I VALUE 1. DEFINE increment. ADD ...

What are Field Symbols in SAP ABAP Field Symbols  Field symbols and data references are used to access data objects dynamically in ABAP programs. without knowing the name attributes till run time ,using field symbols ,we can access and pass data objects. When we address a field symbol, the system works with the contents of the data object assigned to it, and not with the contents of the field symbol itself. Field symbols are placeholders or symbolic names for other fields. They do not physically reserve space for a field, but point to its contents. Whenever you address a field symbol in a program, you are addressing the field that is assigned to the field symbol. After successful assignment, there is no difference in ABAP whether you reference the field symbol or the field itself. You must assign a field to a field symbol before you can address it in a program. You can create field symbols either without or with type specifications. If you do not specify a type, the...
