Hi,

For eg, if you want to display the result of FM in webdynpro input field.

IN wddoinit method of view that is created by you,

DATA:

node_node1 TYPE REF TO if_wd_context_node,

elem_node1 TYPE REF TO if_wd_context_element,

stru_node1 TYPE wd_this->element_node1 ,

item_attr1 type string.

• You can use pattern to call the FM

CALL FUNCTION 'FUNCTION_NAME_XXXX'

importing

var1 = item_attr1

.

• YOu can use webdynpro code wizard to generate this code. ( read attribute )

• navigate from <CONTEXT> to <NODE1> via lead selection

node_node1 = wd_context->get_child_node( name = wd_this->wdctx_node1 ).

• get element via lead selection

elem_node1 = node_node1->get_element( ).

• get single attribute

elem_node1->set_attribute(

EXPORTING

name = `ATTR1`

value = item_attr1 ).

If you want more information please go through the tutorials available in sdn or visit

help.sap.com and search for webdynpro abap.

Hi,

Calling of FM is same like as you call in normal programs.

After getting the data from FM, you have to bind the the structure to the node or set the the value to the attribute which is used for your inputfield.
