What is the description of profile option : PO: Override Unvalidated Invoices check

We would like to know the impacts related to put the profile PO: Override Unvalidated Invoices check = Yes to allow us to modify the Purchase order (change amount in BWC) even if there is unvalidated invoice related to the Purchase Order (not related to the line that we would like to modify).

This is to prevent the error : You cannot perform Change Amount action because there are Unvalidated Invoices.

Thank you
