Standard Table to be updated based on User action

Question

Hi Friends ,
i have a requirement , its a report and in that based on the user action ( if the user checks a check box that is available in the output screen of the report and saves it)  the value should be updated in a standard table as 'X'. I have appended the field in the standard table and now i need to write a logic at user command to populate the zfield that i have added in the table based on the user's input. Can someone suggest me how to proceed further on this ? Kindly let me know if you have any sample piece of code related to this scenario...
thanks in advance.

HI,
Usually we can udpate the tables using UPDATE statement.
But SAP will not suggest to use these statements which will hit the table directly. We need to use the standard transactions to create or update the standard tables.
For eg: you are using a ztable.
then once your report is ready, then use the user_command form ( for ALV) .
fetch the records where the user have selected the records ( check box = 'X").
*&      Form  USER_COMMAND
FORM user_command USING g_ucomm     TYPE sy-ucomm
gs_selfield TYPE slis_selfield                                          .
  CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    IMPORTING
      e_grid = ls_ref1.
  CALL METHOD ls_ref1->check_changed_data .
this will update the check box values in your internal table.
now you can use
loop at itab into wa where check eq 'X'.
fill your final internal table where you need to update the table.
endloop.
loop at newtable.
update ztable set value = 'X'
where keyfield = w_keyfield.
if sy-subrc eq 0.
message s000.
endif.
endloop.
endform.
