Create AMDP class and fetch data based on student branch*

                                                 Refer - Introduction to AMDP

                                                 Example - Sample AMDP example


Step 1: Right click on ABAP project -- New -- ABAP class.

Step 2: Select package, Give class name and description.

Step 3: Click and next and click on finish.

Step 4: Write Code.

CLASS ycl_ab_amdp_stu1 DEFINITION

  PUBLIC

  FINAL

  CREATE PUBLIC .

 

  PUBLIC SECTION.

    INTERFACES : if_amdp_marker_hdb.

    TYPES: begin of ls_stu,

           stu_id TYPE ystu_id,

           stu_name TYPE ystu_name,

           stu_branch TYPE ystu_branch,

           stu_marks TYPE ystu_marks,

           END OF ls_stu.

    TYPES: lt_stu TYPE TABLE of ls_stu.

    Class-METHODS: fetch_data IMPORTING VALUE(stu_bra) TYPE ystu_branch

                        EXPORTING VALUE(lt_data) TYPE lt_stu.

  PROTECTED SECTION.

  PRIVATE SECTION.

ENDCLASS.

CLASS ycl_ab_amdp_stu1 IMPLEMENTATION.

METHOD fetch_data BY DATABASE PROCEDURE FOR HDB

                  LANGUAGE SQLSCRIPT

                  OPTIONS READ-ONLY

                  USING YTL_AB_STU_DET.

      lt_data = select stu_id,

                       stu_name,

                       stu_branch,

                       stu_marks

                       from YTL_AB_STU_DET

                       where stu_branch LIKE :stu_bra;

ENDMETHOD.

ENDCLASS.

Step 5: Calling AMDP class in report.

    REPORT yr_call_amdp_stu1.

    PARAMETERS: p_branch TYPE ystu_branch.

    START-OF-SELECTION.
      DATA: lf_obj TYPE REF TO ycl_ab_amdp_stu1.
      CREATE OBJECT lf_obj.

      CALL METHOD ycl_ab_amdp_stu1=>fetch_data
        EXPORTING
          stu_bra = p_branch
        IMPORTING
          lt_data = DATA(lt_stu).

      cl_demo_output=>display_data( name = 'Student Details' value = lt_stu ).


Table data.


Input.



Output.

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 .
