Web module column link to go in detail query is disabled

Question

Hi,
I have a query only module. Once I query the module, it shows list of
matching records. My problem is I am not getting a link in any queried
columns to see the details of selected record.
I don't know which option it will enable it.
Pl. help!! Thanks in advance.

Hi Ingmar,
Implement 'ON_CLICK_EVENT' in the same view where u have ALV. Clicking on the link in the cell using link to action gives you the following information which u can use (pass to other view etc..) -
COLUMN_ID
INDEX
ATTRIBUTE
VALUE
You can read these values and store them in a node.
Create one node in the view by name 'EVENT_PROPERTIES' with attributes 'NAME' and 'VALUE' of type string both and use the below code in on_click_event. Here I am navigating to the next view after clicking the link, you can do whatever u want depending on ur requirement.
  DATA: lr_node TYPE REF TO if_wd_context_node,
        lt_event_properties TYPE if_models_list_view=>elements_event_properties,
        ls_event_properties TYPE if_models_list_view=>element_event_properties.
  FIELD-SYMBOLS: <l_value> TYPE ANY.
fill internal table
  ls_event_properties-name = 'COLUMN_ID'.
  ls_event_properties-value = r_param->column.
  APPEND ls_event_properties TO lt_event_properties.
  ls_event_properties-name = 'INDEX'.
  ls_event_properties-value = r_param->index.
  APPEND ls_event_properties TO lt_event_properties.
  ls_event_properties-name = 'ATTRIBUTE'.
  ls_event_properties-value = r_param->attribute.
  APPEND ls_event_properties TO lt_event_properties.
  ASSIGN r_param->value->* TO <l_value>.
  ls_event_properties-name = 'VALUE'.
  ls_event_properties-value = <l_value>.
  APPEND ls_event_properties TO lt_event_properties.
navigate to context node EVENT_PROPERTIES
  lr_node = wd_context->get_child_node( 'EVENT_PROPERTIES' ).
bind internal table to context node
  lr_node->bind_table( lt_event_properties ).
  wd_this->fire_to_pi_main_view_plg( ).
