Hello,

Not sure what you meant by blank screen.

If you want to clear/reset the values of the fileds, then you can invalidate the corresponding context node.

Refer to the following thread:

Hope this helps!

Hello,

Here is the code snippet:

    DATA lo_nd_node_flight TYPE REF TO if_wd_context_node.

    DATA lo_el_node_flight TYPE REF TO if_wd_context_element.
    DATA ls_node_flight TYPE wd_this->element_node_flight.

*   navigate from <CONTEXT> to <NODE_FLIGHT> via lead selection
    lo_nd_node_flight = wd_context->get_child_node( name = wd_this->wdctx_node_flight ).

    lo_nd_node_flight->invalidate( ).

hi Deepika,

IF_WD_CONTEXT_NODE has several methods and one of them is invalidate.

Your code snipet could be like this.

DATA lo_nd_yournode TYPE REF TO if_wd_context_node.

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

lo_nd_yournode = wd_context->get_child_node( name = wd_this->wdctx_yournode ).

• invalidate the node

lo_nd_yournode->invalidate( ).

PS : replace the yournode with your nodename.
