ALV with Integrated Data Access

Hicron /// Technical Supremacy

ALV with IDA: IntroductionMost important changes / improvements

• Real-time, regardless size of output table

• Only VISIBLE rows are copied from Database• Every scroll is a „separate” SELECT statement• Data volume transfered from DB to application server is drastically reduced

• Code-to-data paradigm (aka Code Pushdown)Data intensive operations moved to database.Tools: CDS View, HANA View (using SQL Script)

• Application layer divided into two areas:• Orchestration Logic – handles business processes• Calculation Logic – performs operations on data

ALV with IDA: Basic Components• Support for any DB – all data is buffered in internal table

• Drill-down• Aggregation• Grouping

• Fuzzy search• Integrated text search

ALV with IDA: Programming interface• Simple program in two lines   DATA(lo_alv) = cl_salv_gui_table_ida=>create( iv_table_name =  'BSEG' ).  lo_alv->fullscreen( )->display( ).

• Building of ALV object is more object-oriented, good example:

  DATA(lo_cond_factory) = lo_alv->condition_factory( ).  DATA(lo_conditions) = lo_cond_factory->covers_pattern( name = 'MATNR'                                                         pattern = '*215*' )->and(                        lo_cond_factory->equals( name = 'PSWSL'                                                 value = 'PLN' ) ).

  lo_alv->set_select_options( io_condition = lo_conditions ).

• Fieldcatalog trimmed, organized and improved

lo_alv->field_catalog( )->display_options( )->set_formatting(    iv_field_name                  = 'SHKZG'    iv_presentation_mode           = if_salv_gui_types_ida=>cs_presentation_mode-description ).

ALV with IDA: Improvements• Enable layout persistence and set options

  go_alv_ida->layout_persistence( )->set_persistence_options(      is_persistence_key  = VALUE #( report_name = sy-repid )

  lo_alv->toolbar( )->enable_listbox_for_layouts( ).

• Build DB columns via Views, using enhanced SQL syntax and scripts

Build application columns using „calculated fields” (like traffic lights)

Can be used in multiple reports!

• Built-in authority checks  lo_alv->add_authorization_for_object(      iv_authorization_object = 'V_VBRK_VKO'      it_activities           = VALUE #( ( auth_field = 'ACTVT'   value = '03' ) )      it_field_mapping        = VALUE #( ( auth_field = 'VKORG' view_field = 'VKORG' ) )  ).
