ABAP examples

Quick answer

These embody the core habits: use ALV for output, select only needed data with a WHERE, read into internal tables rather than looping the database, and write clear, typed code.

Key takeaways

  • Watch out: SELECT in a loop, the classic performance killer.
  • Worked examples: a simple report with alv, efficient database access, what the examples teach.
  • How ABAP examples fits into SAP development and the wider SAP landscape

A simple report with ALV

REPORT z_open_pos.
SELECT ebeln, ebelp, matnr, menge FROM ekpo
  INTO TABLE @DATA(lt_items) UP TO 100 ROWS.
cl_salv_table=>factory( IMPORTING r_salv_table = DATA(lo_alv)
                        CHANGING t_table = lt_items ).
lo_alv->display( ).

Efficient database access

" read once into a table, then work in memory (never SELECT in a loop)
SELECT matnr, maktx FROM makt
  FOR ALL ENTRIES IN @lt_items WHERE matnr = @lt_items-matnr
  INTO TABLE @DATA(lt_texts).

What the examples teach

These embody the core habits: use ALV for output, select only needed data with a WHERE, read into internal tables rather than looping the database, and write clear, typed code. Adapt them into your own reports and classes.

Common pitfalls

  • SELECT in a loop, the classic performance killer.
  • Hand-coded output instead of ALV.
