lv_hlp_str TYPE string VALUE 'DYNCONT_1',

lr_trans_cont TYPE REF TO cl_wd_transparent_container.

lr_container ?= view->get_element( 'ROOTUIELEMENTCONTAINER' ).

lr_trans_cont->set_layout_data( lr_matrix_head ).

lr_container->add_child( lr_trans_cont ).

Hi Felix,

You need to set the layout first and then set the layout data. Use the method cl_wd_matrix_layout=>new_matrix_layout. Do a set_layout on the container and then do set_layout_data. That should solve your problem.
