Hi William,

I am writting a sample code for you :

go to code wizard, select your node VBAk (where you have the attribute VBLEN )

and select the attribute. Now code will be automatically generated.

DATA LO_ND_VBAk TYPE REF TO IF_WD_CONTEXT_NODE.

DATA LO_EL_VBAk TYPE REF TO IF_WD_CONTEXT_ELEMENT.

DATA LS_VBAk TYPE WD_THIS->ELEMENT_VBAk.

DATA LV_VBLEN TYPE WD_THIS->ELEMENT_VBAk-VBLEN.

• navigate from <CONTEXT> to <VBAk> via lead selection

LO_ND_VBAk = WD_CONTEXT->GET_CHILD_NODE( NAME = WD_THIS->WDCTX__VBAk ).

• get element via lead selection

LO_EL_VBAk = LO_ND_VBAk ->GET_ELEMENT( ).

• alternative access via index

• lo_el_VBAk = lo_nd_VBAk ->get_element( index = 1 ).

• @TODO handle not set lead selection

IF LO_EL_VBAk IS INITIAL.

ENDIF.

• get single attribute

LO_EL_VBAk ->GET_ATTRIBUTE(

EXPORTING

NAME = `VBLEN`

IMPORTING

VALUE = LV_VBLEN ).

Now based on the value LV_VBLEN select values from database table and fill the internal table.

DATA LT_VBAk TYPE WD_THIS->ELEMENTSVBAk. " this the table to keep the values

select VBLEN ERDAT ERNAM AUDAT from VBAK into table LT_VBAk where VBLEN = LV_VBLEN.

Now you can bind the table to appropriate node.

I know it doesn't help you now, but for the next Enhancement Package we developing new functionality to trigger the onEnter event handler upon the close of the value help. This should make the "hack" of using the WDDOMODIFYVIEW for such logic unnecessary.

Can we use IF_WD_CONTEXT_ELEMENT->IS_SELECTED method to check and give any condition there........is it possible!

Hi William,

How you will use this ?

here i told you that we have to use appropriate action handler to catch the proper action and then you have to code there accordingly.

there is no action handler when you select any value from search help.So how you will catch the action? Where will you use the method.

Hi William,

There is no other way as of now other than coding in wddomodify. But as Baskaran said it is not a good practise.

Here in web dynpro we have to work with several action & action handler. Now as of my knowledge we dont have any action handler when select any value search help.

wddomodify runs every time whenever the view gets changed so the performance gets effected.

If it is essential then do the coding like get the details.of erdat, ernam based on your input in wddomodify.

Hi William,

As far as i know you do not have any event to subscribe when data is selected on the Search help. one 'dirty ' way you might try is to code in wdddomodifymethod of the view, check if the value in the value help input field is changed and based on that fill the other inputfields.

After value help popup is closed control come along the wddomodify method. However this is not a good practice to do so and it is for that reason not recommended here in forum.
