Hi,
As you are tracking changes in ALV data you must define a event handler for ALV evenr ONDATA_CHECK.
On defining an event handler you will be getting a structure called t_param.
It contains an element called t_deleted rows.
See this code to have an idea.
method ONDATACHECK .
  DATA: x_delete_row LIKE LINE OF r_param->t_deleted_rows.
  "      i_addr_factr TYPE STANDARD TABLE OF ycot_addr_factr,
   "     x_addr_factr LIKE LINE OF i_addr_factr.
TYPES t_proj_constr TYPE ycot_proj_constr.
  FIELD-SYMBOLS: <fs_row> TYPE t_proj_constr.
  IF wd_comp_controller->ya_optyp = 'DELETE'.
    LOOP AT r_param->t_deleted_rows INTO x_delete_row.
      "x_addr_factr ?= x_delete_row-r_value.
      ASSIGN x_delete_row-r_value->* TO <fs_row>.
    DELETE FROM ycot_proj_constr  WHERE plant = <fs_row>-plant
                                 AND   yr_nbr = <fs_row>-yr_nbr
                                 AND   period = <fs_row>-period
                                 AND  billback_pr_fmly = <fs_row>-billback_pr_fmly
                                 AND  prd_nm = <fs_row>-prd_nm.
  ENDLOOP.
I hope it helps.
