To show the BOM of an assembly, there must be a table in the drawing with a repeat region containing at least the report symbol for the report index number (rpt.index) and the model name (asm.mbr.name). you can also shown the quanity of each by going to the table regions menu and selecting attributes. set this to no duplicates this will list each component only once but change the quanity for each time it is used. for more info check the help center under tables and Bom. If you want to use excel you can go to the insert menu and select object, then choose create from file and browse to find your table. I have not used this function I only remember it from school.
