We are in the context

of creating assembly and disassembly. It is observed that the disassembling BOM

has no connection to assembling BOM, so we cannot speak here about

disassembling at all.  When we disassemble something logically, we expect it is 100% reversal of this what was assembled.  Moreover, not even in the context where we

mark the components of assembly and disassembly against each other, the sum of

the BOM components do not equal to the BOM head in disassembling, so we cannot

call it BOM either, as it does not fulfill the basic BOM functionality.
