how calculate the values in column only for checked rows for ALV table

[Former Member]

Hi, experts. I'm beginner in Web Dynpro.

I have some table ALV with checkbox column. I need calculate the values in column for that rows where checkbox is checked ( = ‘X’) and display sum in corresponding column (Price).  How its making using aggregate property of alv for column (cl_salv_wd_aggr_rule), but I need do it only for checked rows.

Thank you very much.

How can I do it ?

Alex, instead of trying to alter the way standard aggregation work I would suggest to put a total row at the bottom which will show the total based on the check box state.

For the aggregation rule functionality available you can check this link.

Read the node at first as a table operation.  Fallow the codes below.

i is

DATA lo_nd_alv_main TYPE REF TO if_wd_context_node.
     DATA lt_alv_main TYPE wd_this->Elements_alv_main.
     DATA ls_alv_main TYPE wd_this->Element_alv_main.
 *   navigate from <CONTEXT> to <ALV_MAIN> via lead selection
     lo_nd_alv_main = wd_context->get_child_node( name = wd_this->wdctx_alv_main ).
     lo_nd_alv_main->get_static_attributes_table( importing table = lt_alv_main ).
     delete lt_alv_main where price = 'X'.

This will delete the checked box values from your internal table and  by looping that table you can do as,

loop at lt_alv_main into ls_alv_main.
CALL METHOD lv_value->if_salv_wd_field_settings~get_field
     EXPORTING
       fieldname = 'LUGGWEIGHT'
     RECEIVING
       value     = lr_field_amnt.
   CALL METHOD lr_field_amnt->if_salv_wd_aggr~create_aggr_rule
     EXPORTING
       aggregation_type = if_salv_wd_c_aggregation=>aggrtype_total
     RECEIVING
       value            = lv_aggr_rule.
endloop.

This is not right algorithm. The sum of column is calculated for all rows, not only for thats rows where checkbox is 'X'.
