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.
