What is best practice for use of the AR Invoice Line Information DFF?

This DFF has 15 attributes available. Oracle maps them directly from the source context (For invoices created from a sales order, order line attributes1-15 are populated in the same attributes on the invoice line. Same goes for Service Contracts)

This can get messy with things populating that aren't desired and unaware admins could create segments on the record not knowing the integration.

What is best practice for managing this DFF? Require all attributes to be in a context that mirror that of it's source module? Manipulate attribute1-15 in the interface table with a preprocessor?

Thank you in advance for your thoughts.
