HI Paolo
I didn't notice BT11H_OPPT and i thought that you are working with Search Comp
... Get the data from POPUP ( Context node data )
lr_context_node TYPE REF TO cl_bsp_wd_context_node,
lr_current TYPE REF TO if_bol_bo_property_access,
lr_context_node = <popupinstance>->get_context_node( iv_cnode_name = 'NODENAME' ).
lr_current = lr_context_node->collection_wrapper->get_current( ).
now from LR_CURRENT get the Attribute <value>which you needed
....Now from the view get the entity and set the <value> to the field which you retrieved above
