ABAP Source code

START-OF-SELECTION.

*1.. Create object reference for ALV with IDA
*...  based on CDS View
DATA(lo_alv_display) = cl_salv_gui_table_ida=>create_for_cds_view( 
                                   iv_cds_view_name = 'zcds_total_stock' ).

*2.. Create Aggregation rule
DATA: ls_aggr_rule  TYPE if_salv_gui_types_ida=>ys_aggregation_rule,
      lt_aggr_rules TYPE if_salv_gui_types_ida=>yt_aggregation_rule.

ls_aggr_rule-field_name = 'TOTAL_STOCK'.
ls_aggr_rule-function   = if_salv_service_types=>cs_function_code-sum.
APPEND ls_aggr_rule TO lt_aggr_rules.

lo_alv_display->default_layout( )->set_aggregations( lt_aggr_rules ).

*3... Display ALV
  lo_alv_display->fullscreen( )->display( ).

Output

Sub Totals

Sub Totals in ALV with IDA can be achieved by using both Sorting Rule and Aggregation Rule.

To define a subtotal on a particular column first you need to define sorting rule by using the SET_SORT_ORDER( ) and then apply aggregation rule by using method SET_AGGREGATION( ).
