VKM1 not showing consignment orders

VKM1 not showing drop ship consignment fill up orders. We use Item Category ZTSP ( 3rd party item cateogry with Credit active check in VOV7) for KB ( consignment fill up) orders. Once after order created, system is doing automatic credit check and it shows credit blocked under SO header status tab. Where as these orders are not appeaing in VKM1.

for normal items it is working fine. What triggers this????
