hi, Sana.

Okay, in dynamic ALV realizing OVS is the same with normal.

(1). Add the component "WDR_OVS" as one used component in your WD.

(2).In your dynamic ALV columns, set the OVS input mode to your desired column. Just one EXAMPLE:

* Get ALV columns
  CALL METHOD l_value->if_salv_wd_column_settings~get_columns
    RECEIVING
      value = lt_columns.
* Loop columns
  LOOP AT lt_columns INTO ls_column.

*set OVS for the column
    if  ls_column-id = 'CARRID'.
         "first get your Context NODE information
        co_dynnode_info = lo_node->get_node_info( ).
        "second, set the OVS for the context attribute
        CALL METHOD co_dynnode_info->set_attribute_value_help
           EXPORTING
                name            = ls_column-id
                value_help_mode = if_wd_context_node_info=>c_value_help_mode-ovs
                 value_help      = 'OVS_COMP'.  "Your OVS used component
    endif.

(3).Now, you can implement the event "OVS" of your OVS used component, for example in Component controller.

Note: method type (Event handler); Event (OVS); Component (your declared OVS used component)

Now, you can realize it as usual.

I don't know whether it is clear, hope it can help u a little.

Very glad to discuss with u about this topic.

Best wishes.

Hello Can Tang,

It was the excatly the one which i was searching and trying to achive it. Thanks for the quick reply.

I tried to follow the exact process described by u. But still the column which i want is not displayed as F4 rather it is just greyed out .

Steps Followed :

1. created used component OVS_PHASE and used it in Component controller.

2. loop at columns

lr_root_info = node->get_node_info( ).

CALL METHOD lr_root_info->set_attribute_value_help

EXPORTING

name = lr_column_all->id

value_help_mode = if_wd_context_node_info=>c_value_help_mode-ovs

value_help = 'OVS_PHASE'.

this is what exactly i did ..But Still my column in not displayed as F4 ... Suggest me if i am missing anythng..

Sana.

hi, Sana.

Thanks and glad to discuss with you about this topic.

In addition to the coding you post out,

First check you define the column as "Read-Only", i guess maybe you use "Input field" as your Cell editor in ALV, pls follow:

*   Init input control
    CREATE OBJECT lr_input
      EXPORTING
        value_fieldname = ls_column-id.
    lr_column->set_cell_editor( lr_input ).
   lr_input->set_read_only( abap_false ).

And, the most important, you should implement your OVS event handler:

3).Now, you can implement the event "OVS" of your OVS used component, for example in Component controller.
Note: method type (Event handler); Event (OVS); Component (your declared OVS used component)
Now, you can realize it as usual.

Hope it can help you a little,

Best wishes.
