ALV data_changed with deleted rows

Question

I want to access cell value in my ALV OOPS instance for a deleted row.

LOOP AT er_data_changed->mt_deleted_rows INTO ls_del.
  CALL METHOD er_data_changed->get_cell_value
    EXPORTING
      i_row_id    = ls_del-row_id
      i_fieldname = 'FIPEX'
    IMPORTING
      e_value     = lv-fipex.
ENDLOOP.

but lv-fipex is always blank. Why get_cell_value doesn't work with deleted rows? What can I use for this?

Answer 1

This method seems to return data only if you modify a particular cell or cells of a row. In order to achieve what you want read directly from the internal table used as CHANGING parameter in the call of method SET_TABLE_FOR_FIRST_DISPLAY. The actual deletion occurs after the event DATA_CHANGED so you can do that as the data to be deleted are still in the internal table.

Look at this example (you have to create the screen and status 100 by yourself).
