global function form_loaded 
create=button=text=Print,name=printlocation 
end global 
 // ******* Event dw_master_item_button_printlocation_click ******** 
 // Created 2020/10/01 by lls@boyum-it.com 
 global function dw_master_item_button_printlocation_click 
 tools=auswahl=location,Choose item=S= =<location>
