If not using the Create Warehouse Receipt functionality from the "Landed Cost Container" screen (which allows you to create a single "Warehouse Receipt" for a single "Landed Cost Container") you are able to filter on a Landed Cost Container No when selecting the Use Filters to get Src. Docs function on a "Warehouse Receipt".

When selecting this option, a new Field has been to the "Source Document Filter Card" screen called LC Container No Filter which can be used to define a specific Container.  When running this Function, all "Purchase Order Lines" which have the same LC Container No will be brought onto the "Warehouse Receipt" for you.
