Hi meenachi,.

Here the problem is with the quotes ( 'CUST_MAT_CODE' )

your code should be like this

  ovs_callback_object->context_element->set_attribute(

                               name  = ( `CUST_MAT_CODE` ) instead u write this 'CUST_MAT_CODE '

                               value = <ls_selection>-this should be a field name on which field u r using F4 button ).

Thanks and regards,

Vijay

did you try to bind value in table

[Former Member]

TYPES : BEGIN OF ty_inv,

          matnr type matnr,
          END OF ty_inv.



  DATA : lt_inv TYPE STANDARD TABLE OF ty_inv,

         wa_inv TYPE ty_inv.



* Logic to Enable Table Control Columns

  DO 10 TIMES.

    APPEND wa_inv TO lt_inv.

  ENDDO.



  DATA lo_nd_complaint TYPE REF TO if_wd_context_node.

  lo_nd_complaint = wd_context->get_child_node( name = wd_this->wdctx_complaint_items ).

  lo_nd_complaint->bind_table( new_items = lt_inv set_initial_elements = abap_true ).

I wrote this code in my doinit..

actually this code to enable table rows.. is it correct?

In phase_3 you should modify particular row  from table with ovs result and again bind it with node.

  In phase 3 i wrote this coding..

WHEN if_wd_ovs=>co_phase_3.

        ASSIGN ovs_callback_object->selection->* TO <ls_selection>.

        IF <ls_selection> IS ASSIGNED.

        ovs_callback_object->context_element->set_attribute(

                               name  = `CUST_MAT_CODE`

                               value = <ls_selection>-CUST_MAT_CODE ).

whether i need to bind again?

there instead of

ovs_callback_object->context_element->set_attribute(

                               name  = `CUST_MAT_CODE`

                               value = <ls_selection>-CUST_MAT_CODE ).

you have to get table row from which ovs is executed. modify that particular row and bind it again with node

steps to do this :-

1. get element based on lead selection. by using if_wd_context_node method get_lead_selection.

2. get row by using if_wd_context_element method get_static_attribute.

3. modify this row .

4. bind agiain with element.

reward point if helpful

Hi Meena,

Your phase 3 code looks correct. The object ovs_callback_object->context_element is the context element which requested the OVS input help, so you don't need to read the lead selection manually. Perhaps it is a problem with the quotes as Vijay suggested. Try retyping 'CUST_MAT_CODE' with single quotes from the keyboard instead of a copy-paste from elsewhere. If that doesn't work, try setting a break-point and seeing what happens inside the call to

ovs_callback_object->context_element->set_attribute; it sounds like maybe it isn't finding context attribute 'CUST_MAT_CODE'. And if that doesn't work, could you please post the whole of your on_ovs method?

If it is helpful, you can also check your component usage and on_ovs code against this document, .

Cheers,

Amy

Hi Meena,

Yes, I use this same approach to append initial rows to a table that is ready for user input. You can also shorten the code by using APPEND INITIAL LINE and eliminate the need for an explicit workarea...

method supply_table .
 
   data lt_table type wd_this->elements_table.
 
   do 5 times.
     append initial line to lt_table.
   enddo.
 
   node->bind_table(
     new_items                 = lt_table
     set_initial_elements = abap_true ).
 
 endmethod.

hi amy,

Not only for this field for entire row f4 is not working..

hey Amy,

Thanks. It was working now.

The issue is due to context binding in table control
