Oracle Maintenance Cloud/Fusion GL Account Question

As part of Oracle Fusion Cloud Maintenance Management module, we are looking for Oracle best practices/ recommendation about which GL account is/ should be used as a default to charge the routing maintenance cost (like - Preventive or Corrective maintenance) ?

And For an overhaul maintenance which increases the assets usage, life, capability or value, what does Oracle recommends on whether to manage such maintenance through on Internal Capitalization Project or though a regular maintenance workorder ?

Can any one reply to this question. Thank You
