Exceptions in abap

 Exceptions: - Exception is nothing but run time error. We handle these exceptions by using TRY & CATCH blocks.

Note: - CX_ROOT is used to store the error.


Code

REPORT ZAJAY_EXCEPTION_EXMP1.
class lcl_excep DEFINITION.
  PUBLIC SECTION.
  METHODS l_m_excep IMPORTING imp_var1 type i imp_var2 TYPE i EXPORTING e_sum type i.

  ENDCLASS.

CLASS lcl_excep IMPLEMENTATION.
  METHOD l_m_excep.
    TRY.
      e_sum = imp_var1 / imp_var2.


    CATCH CX_ROOT.
      MESSAGE 'CAN NOT DEVISIBLE BY ZERO' TYPE 'I'.

    ENDTRY.

    ENDMETHOD.
  ENDCLASS.

  START-OF-SELECTION.
  PARAMETERS: p1 type i,
              p2 TYPE i.
  data : sum type i.
  data obj type REF TO lcl_excep.
  create OBJECT obj.
  obj->l_m_excep(
    EXPORTING
      imp_var1 = p1
      imp_var2 = p2
    IMPORTING
      e_sum    = sum
  ).
  IF SUM <> 0.

    WRITE: 'divisible of two numbers is ', sum.

  ENDIF.

Notes

    * If you don't use exception concept, if any error comes then raise a dump and program terminates.

    *  If you are using exception concept, if any error comes it catches the exception and raise message and program execute successfully.

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...
