When converting assets, is the asset acquisition detail "amount" required? If not, is anything misse

The issue we are having is that some assets do not have an acquisition date in the legacy system. Without an acquisition date, a row is not created on the the ASSET_ACQ_DET table for these assets and therefore the ASSET_ACQ_DET.AMOUNT cannot be captured. This doesn't seem to cause any issues in running depr calc, depr close, accounting entries, or in loading the reporting tables. Would not having the acquisition amount cause an issue anywhere in the system?

The biggest issue that we have noticed is that it creates a discrepancy in the validation files. I would like to be confident in saying that this field is not required.
