Hey all, I am having a problem where I cannot use an assembly as a sub assembly on my BOM revision and I cannot figure out why. These are both Lot Numbered Assemblies with BOM revisions attached. I want to use ASSM1 as a SUB assembly of ASSM2 and when looking at the Components of Rev 1 of ASSM2 no assembly items are available. Any ideas? Edited for clarity

check both assemblies are setup for the same subsidiary(s), also on the assembly record, if the chekcbox for mark subassemblies as phantom is ticked
