Dynamic mapping of function_elements in ALV.

Question

Hi Experts,
    I need to do a dynamic external mapping of function_elements node in my code. How we can achieve this?
Any specific method can be used to do the mapping for the function_elements in ALV.
Thanks & Regards,

Answer 1

I have created a node that has a attribute (check the cardinaltiy what functional elements is expecting use the same cardinaltiy)
Now, go to the functional elements node map this node to that node.
I have used this attribute for dropdown.
to fill that attribute, get node info-> use valuset to fill that.
For ALV->
DATA:
    lo_function  TYPE REF TO cl_salv_wd_function,
    lo_drk_year TYPE REF TO cl_salv_wd_fe_dropdown_by_key,
    lo_fe_year   TYPE REF TO cl_salv_wd_fe.
    CREATE OBJECT lo_drk_year
      EXPORTING
        selected_key_elementname = 'YEAR'.  "ATTRIBUTE NAME
    IF lo_drk_year IS BOUND.
      CALL METHOD lo_drk_year->set_label_text
        EXPORTING
          value = 'Select a Year'.
      lo_fe_year ?= lo_drk_year.
    ENDIF.
    CALL METHOD _o_ref_alv_emp_model->if_salv_wd_function_settings~create_function
      EXPORTING
        id    = 'FUNCTION2'
      RECEIVING
        value = lo_fun_year.
    IF lo_fun_year IS BOUND.
      CALL METHOD lo_fun_year->set_editor
        EXPORTING
          value = lo_fe_year.
    ENDIF.
