Tax Box Reporting - Asset Flag (Transaction Input Factor) - what does Oracle use to set it on?

Summary:

Need to understand what criteria Oracle uses to set the ASSET_FLAG on tax transactions, for use in the Tax Box Allocations process.

Content (required):

In tax box reporting, Oracle provides the "Asset" transaction input factor which can be used as the determining factor on a condition set. Using it leads to the criterion of "ASSET_FLAG" which has possible values of "Y" or "N".

What is not clear is what criteria Oracle uses to make the "Y" or "N" decision. Is it as simple as the GL account type on the transaction or are there other factors which are used?
