Filtering a report on the new forms

A report link field can match on any field with no relationship required.  So set up a Report Link on the Account table where you configure the left side with the Account # of the "Parent" and then on the right side navigate to the same App and then scroll down to locate the Account# on the Requests table.

Then just put the Report Link on the form to show as a Report.

Note that this is likely the only place in Quickbase where during that Navigation it causes what will be seen by your browser as a pop up so once in your life on that Browser you will need to click to always allow pop ups from Quickbase.
