Object Model - cl_salv_hierseq_table Check box in the parent entry

Question

Hi,
I am doing a report with cl_salv_hierseq_table (Object Model) , in that i  need to put a check box in the t_table_level1 level. I know that SALV is not have an option to edit.
My requirement is from the list user select multiple parent entries (ie t_table_level1 ) and selected entries must be converted to web template and send to HTML repository.
Currently i am struck up with creating a check box in HIERSEQ list
Any Info?

Hi aRs.  You need to use the class CL_SALV_SELECTIONS for this.  See here,  
DATA: gt_parent TYPE TABLE OF scarr.
DATA: gt_child TYPE TABLE OF sflight.
DATA: gr_table  TYPE REF TO cl_salv_hierseq_table.
DATA: gr_selections TYPE REF TO cl_salv_selections.
DATA: lt_binding TYPE salv_t_hierseq_binding.
DATA: ls_binding TYPE salv_s_hierseq_binding.
SELECT * FROM scarr INTO CORRESPONDING FIELDS OF TABLE gt_parent.
SELECT * FROM sflight INTO CORRESPONDING FIELDS OF TABLE gt_child.
ls_binding-master = 'CARRID'.
ls_binding-slave  = 'CARRID'.
APPEND ls_binding TO lt_binding.
CALL METHOD cl_salv_hierseq_table=>factory
  EXPORTING
    t_binding_level1_level2 = lt_binding
  IMPORTING
    r_hierseq               = gr_table
  CHANGING
    t_table_level1          = gt_parent
    t_table_level2          = gt_child.
gr_selections = gr_table->get_selections( level = 1 ).
gr_selections->set_selection_mode( cl_salv_selections=>if_salv_c_selection_mode~multiple ).
gr_table->display( ).
This will give you the checkboxes in the parent level, you still need to write the code to get the selected rows.
