AP Invoice line level approval

Summary

AP Invoice line level approval not available

Content

Good day

There is a lot of notes saying that invoice line level approval are available but not supported by Oracle, I found notes that say for some customers it actually works, and other notes saying that it doesn't work.  Does anyone have a clear answer on this as it is quite a common business requirement that an invoice line goes to its cost center for approval.
