Dynamic Detail Component for POWL application

[Former Member]

Dear All ,

I have a POWL application. I need to choose between 2 detail components at runtime based on document type ( Outbound / Inbound Delivery ) in my alv. Can anyone suggest how can we achieve this in the feeder class. As of now i can see that we can only pass one detail component can be given in feeder class.

Hi Vikas,

Hope the below logic will help you to solve your issue,

IF_POWL_FEEDER~HANDLE_ACTION --> Handle action of the feeder class

" Once the selected record is moved to work area using below code,

DATA: l_result_tab TYPE ptrm_powl_web_trips_ext.

FIELD-SYMBOLS: <l_data>         TYPE ptrm_powl_tr_action_data_t,
                                <l_data_line> TYPE ptrm_powl_tr_action_data.

CREATE DATA e_portal_actions-add_wdevent_data TYPE ptrm_powl_tr_action_data_t.
ASSIGN e_portal_actions-add_wdevent_data->* TO <l_data>.

CREATE DATA l_data TYPE  ptrm_powl_tr_action_data.
ASSIGN l_data->* TO <l_data_line>.

READ TABLE c_result_tab INDEX i_action_index INTO l_result_tab.

" Check the value of the 'Document Type' field and based on the same, pass unique indicator to navigate method of the 'Overivew' component like below,

if l_result_tab-doc_type eq '1'. " Outbound Delivery

    <l_data_line>-name = 'DOCTYPE'.
    <l_data_line>-value = '1'.
    APPEND <l_data_line> TO <l_data>.

elseif l_result_tab-doc_type eq '2'. " Inbound Delivery

    <l_data_line>-name = 'DOCTYPE'.
    <l_data_line>-value = '2'.
    APPEND <l_data_line> TO <l_data>.

endif.

e_portal_actions-fire_wdevent = abap_true.

""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""

" 'Navigate' method of overview component

method navigate .

* Field Symbol Definition
  field-symbols: <fs_parameter>    like line of wdevent->parameters,
                         <ft_httpparam>     type powl_namevalue_tty,
                         <fs_httpparam>    type powl_namevalue_sty.

data : lv_doctype type char1.

clear lv_doctype.

  read table wdevent->parameters with key name = 'EVENT_PARAMETERS' assigning <fs_parameter>.

  assign <fs_parameter>-value->* to <ft_httpparam>.

if <ft_httpparam> is assigned.

      read table <ft_httpparam> with key key = 'DOCTYPE' assigning <fs_httpparam>.
      if sy-subrc eq 0.
        lv_doctype = <fs_httpparam>-value.
      endif.

endif.

if lv_doctype eq '1'.
" Call application 1 (Component 1).
elseif lv_doctype eq '2'.
" Call application 2 (Component 2).
endif.

end method.

Hello Vikas,

it needs to be done once only.

Best regards,
