Hi,

I have a same problem. I am getting data from R/3, I am populating one of the columns in a table(direct binding). It is working fine. Whenever user selects one of the values in that column(dropdown), the value is changing to other values in other rows of the column as same value.

Ex:

empl1 epmname1 florida(dropdown)

emp2 epmname1 california (this will change to any other state)

emp2 epmname1 florida (if i select other states - the above staes are become florida) - I believe you got my point.

Please help me out

Thanks...

use use supply function,and bind it to the node for dropdowns.

HI Prosun,

If you code for displaying the description in the OnSelect Event, you will always get the same text for all the rows. You do not need to code anything in the event handler. Just leave it empty (do not delete the event) and try this.

Bind the wages type code to the node info of an attribute in the table (say CODE).

Now, in the table, create two columns, one with 'DropDownByKey' as cell editor and other with 'TextView' as cell editor. Bind property 'selectedKey' of first column to CODE. Bind property 'text' of second column to CODE too.

Now when you select a value in the drop down, the corresponding value will be displayed in the text view.

Also, to attach the values to the node info, follow this.

Say your attribute CODE lies in a node called CTX_TAB. In WDDOINIT of the view (or controller) use the following code.

DATA:

lo_nd_ctx_tab TYPE REF TO if_wd_context_node,

lo_ndinfo_ctx_tab TYPE REF TO if_wd_context_node_info,

lt_value_set TYPE TABLE OF wdr_context_attr_value,

ls_value_set TYPE wdr_context_attr_value.

ls_value_set-value = '01'.

ls_value_set-text = 'One'.

APPEND ls_value_set TO lt_value_set.

ls_value_set-value = '02'.

ls_value_set-text = 'Two'.

APPEND ls_value_set TO lt_value_set.

lo_nd_ctx_tab = wd_context->get_child_node( 'CTX_TAB' ).

lo_ndinfo_ctx_tab = lo_nd_ctx_tab->get_node_info( ).

lo_ndinfo_ctx_tab->set_attribute_value_set( name = 'CODE' value_set = lt_value_set ).

Also, lead selection should be intialized for the node CTX_TAB.

Hi Neha,

thanks for your answer. One custom Function Module is returning me the three table EX_WAGETYPES(Fields wages type),EXWAGETYPE_TEXTS(Fields wages type,desc),EXRETURN(for any errors.).I am populating the drop down from the first table. In view i have table column mapped to wages_type, second column mapped to desc.Now my FM returning me 75 values. It is almost impossible to give them index. Do u have any suggestion for this? What should be my approch?

Hi Prosun,

Instead of using 'DropDownByIndex', use 'DropDownByKey'. This way you will not have to maintain an index. In the ls_value_set (type wdr_context_attr_value), use the wages_type-wage_type as ls_value_set-value and wages_type-desc as ls_value_set-text.

'DropDownByIndex' works on the elements of a node. But 'DropDownByKey' works on the node info.

I tried with this also but result is same.All the rows showing same value.

Hi Prosun,

Can you check the node info while debugging. Does it have the correct values?

I am asking this because I tried the same scenario on a dummy component and it was working fine.
