You need to instantiate a component usage of the ALV. Do that using the following code in your doinit method or the method where you initialize your ALV model. This is assuming that your usage name is 'ALV'.

data: l_ref_cmp_usage TYPE REF TO if_wd_component_usage.

l_ref_cmp_usage = wd_this->wd_cpuse_alv( ).

IF l_ref_cmp_usage->has_active_component( ) IS INITIAL.

l_ref_cmp_usage->create_component( ).

ENDIF.
