Auto-complete rules and EFFs. Are there currently issues in all scenarios?

Summary:

Currently working with describing cases for my current customer and getting different information from different sources on the current state of how and if EFFs are supported by the Autocomplete Rules.

 

As I read the documentation EFFs would be supported but only in general transaction flows (Hire, Transfer etc.) but not in the specific flow “Additional Assignment Information”. https://docs.oracle.com/en/cloud/saas/human-resources/21d/faiau/business-objects-in-autocomplete.html#FAIAU4688432

 

When I have submitted my cases I am pointed to a known issues page that states that similar scenarios may currently be having issues.
