Switch statement.

    

    * From ABAP 7.4 onwards, SAP introduced SWITCH statement.

    * We need to use SWITCH statement instead of CASE statement.

    * In CASE statement, we need to specify the variable which is getting filled in every condition.

    * In SWITCH statement, we need not to mention the variable which is getting filled in every condition. 


CASE (Old).

        REPORT zab_rp_switch.


    PARAMETERS: p_day TYPE i.
    DATA: lv_output(15) TYPE c.

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

* 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...
