Quote Subcontract Info

Hey I am trying to recreate the Quote Worksheet (If anybody has
pulled this off please feel free to shoot it over to me) I am
currently stuck trying to find where the following info is stored.
If you do a quote. Add a subcontract to an operation on a line.
Then go to price breaks and add a Quote Price Break where is that
stored? I am going nuts trying to find it. I am thinking has
something to do with OPMaster or VendPBreak table but either am not
linking correctly or just not looking in the right place. Thanks
