Debugging in SAP ABAP

 

*  Debugging is a process to understand program behavior in runtime.

                                            OR

* Debugging is a technique by which we can find the error, correct the error, detect the error.

*  There are two types of breakpoints

    > Static - User dependent break point


    > Dynamic Break points - User Independent break point

        Syntax - BREAK <USERNAME>

                                                                    OR




Function keys 

        > F5 - Step by step execution.

        > F6 - Line by line execution.

        > F7 - Return.

        > F8 - Append row.

    * When you are using reusable components (function modules, sub routines) - F5, F6 are different.

    * When you have no reusable components - F5, F6 are same.

* Two ways of debugging

    > Put breakpoint on executable statement.

    > /h - transaction {execute /h debugging is on}


System Variables

* SY-SUBRC

            SY-SUBRC = 0   Successful.

            SY-SUBRC < >    Unsuccessful.

* SY-TABIX - Returns current line index inside loop.

* SY-DATUM - Returns current date (default -yyyymmdd).

* SY-UNAME - Returns the username.

* SY-UZEIT - Returns the system time un format ( HH:MM:SS).

* SY-UCOMM - User command.


*  Path to move to a selected line: Debugger- go to statement.

*  Put the breakpoints on keywords in debugging mode (Ex: select call function, message).

*  Deleting breakpoints - permanently deleting the breakpoints.

*  Deactivating the breakpoints - temporary deactivate the breakpoint.

*  Watch point - To monitor the values of variables and internal tables, work area.

                        Breakpoint limit - 30.

                        Watchpoint limit - 10.

New syntax for append- VALUE (new syntax 7.4+) in ABAP

Image
* We use APPEND statement to insert the records at the last of the internal table. * In SAP ABAP new syntax, we can use VALUE expression instead of APPEND statement. * Value expression is a powerful mechanism to declare as well as initialize the internal tables. * It is a powerful utility where we can achieve the result with minimal coding. * Value expression is of 2 types.      -  Define the type before using it with VALUE keyword. The type defined is structure type  or table type.      -  Using # character for type and use it with VALUE keyword. Report REPORT  zab_rp_append_value . TYPES :  BEGIN  OF  ls_stu ,          st_id ( 10 )    TYPE  n ,          st_name ( 15 )  TYPE  c ,         END  OF  ls_stu . DATA :  lt_stu  TYPE  TABLE...

Read statement new syntax in ABAP. (7.4+).

Image
*  Before ABAP 7.4, we used READ TABLE statement to read the first matching record from the internal table  based upon key or index . * In SAP ABAP new syntax, instead of READ TABLE , we can use the table expressions. * We need to use the square bracket [ ], In the square bracket, we need to specify the key or index. * While using table expression, If the table entry does not exist, system throws the exception CX_SY_ITAB_LINE_NOT_FOUND. * Use line_exists statement to check the existence of a record. Report REPORT  zab_rp_read_new . TABLES :   vbak . SELECT-OPTIONS :   s_vbeln  FOR  vbak - vbeln . SELECT  vbeln , erdat , erzet , ernam , auart         FROM  vbak         INTO  TABLE  @DATA ( lt_vbak )          WHERE  vbeln  IN  @s_vbeln . WRITE :   'Index value'  COLOR  5 . READ  T...
