If I right click I'm not seeing a configuration on the assembly name only the assembly name itself. If I change one of the columns to config name / configuration name etc I'm not getting the correct names. With that aside if only configuratiuons 1 and 2 are on the drawing why does it pick 3?
I am not understanding exaclty what you are RMB on. When I select the BOM and then go to the properties I see the tree on the left side. This has a number of headings in it and one of them it Configurations. You should be able to select the one(s) that you want on the drawing.
Sorry I was not understanding your question, it makes sense now. You have inserted an assembly into another assembly and the BOM is pulling the information for that sub assembly from a configuration that is not in the drawing, correct?
Custom properties in the assembly do work as you suggested. Configuration specific props override custom props for that configuration. If a configuration does not have a specific configuration property then it will use the custom properties. So you are correct that you will have to enter that information for each configuration if the information is different. If the information is the same for all configurations then you could enter it once at the custom properties tab and leave it blank at the configuration specific tab.

If you click on your BOM you can check what configuration it is linked to.
