What is `Allow fallback to parent's rules` used for

[pbels1]

In the identification entry there is a field `Allow fallback to parent's rules`.  What is this field used for?

Hi @pbels1,

Below is a snippet from the documentation - https://docs.servicenow.com/bundle/washingtondc-servicenow-platform/page/product/configuration-manag...

Thanks

This states it is only for dependent identification so if my identification rules are independent this will do nothing?  Here is my situation there are rules at hardware and a class that extends from hardware has its own identification rules.  What I want to do is if the rules at the lower class do identify a record, then the Hardware rules will be used.  Can something like this be done?

Hi @pbels1 ,

Yes that is correct, for independent rules it will not apply. Currently we don't have any kind of fallback for independent rules and you will have to make a new identifier entry on the child class for everyone hardware identifier entry you want it to also use.

Hi @Cindy Trieu,

Can you explain what "parent" means in this situation please?  Does it mean the identification entries for the parent *class* of the CI?  Or the identification entries that apply for the parent *CI*, and if so what does "parent CI" mean - based on relationships, or something else?

It would be really helpful if you can give a real example of when "Allow fallback to parent's rules" has been set to true, and what exactly that means when IRE is doing identification.

Thanks
