Hi,
As an example this piece of code will replicate the value from first input field into another input field.
Step 1: Create a View V_DEFAULT.
Step 3: Create a context node INPUT with FIELD1 & FIELD2 as attributes both type string.
Step 2: Add an Input field INP_FIELD1 type STRING inside V_DEFAULT bind value to INPUT-FIELD1.
Step 3: Add another input field INP_FIELD2 TYPE STRING inside V_DEFAULT bind value to INPUT-FIELD2.
Step 4: Select INP_FIELD1 and from the property box create FILLOTHER onEnter event. Double Click and it will open this method in editor.
Now code as below
  DATA lo_nd_input TYPE REF TO if_wd_context_node.
  DATA lo_el_input TYPE REF TO if_wd_context_element.
  DATA ls_input TYPE wd_this->element_input.
  lo_nd_input = wd_context->get_child_node( name = wd_this->wdctx_input ).
  lo_el_input = lo_nd_input->get_element(  ).
  lo_el_input->get_static_attributes(
    IMPORTING
      static_attributes = ls_input ).
  ls_input-field2 = ls_input-field1.   "copy the values
you can write your own logic to get the values for field2 based on the value in field1
  lo_el_input->set_static_attributes(
    EXPORTING
      static_attributes = ls_input ).
Step 5: Activate and create an application
Now if you execute this application and fill any string in input field1 and press enter same value will be replicated in the second input field.
I hope this will help.
