This is NOT something I would just do, especially as the new guy. I would push back a bit and make sure the impact is understood before anyone touches the data.
VendPart : Vendor info about “Our Parts”. Parent to VendPBrk file.
VendPBrk : Vendor Price Break. Contains Quantity/Price purchasing data. Subset of VendPart file. Provides defaults to purchasing. Provides default Cost Breaks for Quote materials/subcontract lines.
Before making any changes, I would build a few BAQs to see how many parts would be affected, then get that information in front of the right people; likely Sourcing and Accounting, before deciding how to proceed.
