How to check for duplicate BOM's

Hi everyone, 

Is there an easy way, to check if there are duplicate BOM's, meaning the
exact same components, quantities, no more no less, in the same facility,
same method, but with 2 (or more) different parents? Does mot matter if the
MBM.BSEQ, MBM.BBUBB, the effectivity dates, or any other fields, including
the BOM notes (MPN) and ref des (MBZ) are different. Basically I'm trying to
look for 2 or more manufactured items that are identical in regards to  the
list of their components, but have different item number. Like if the
engineers designed again an already existing item, but given it a different
item number?
