Report Template Administrator (RDG) - Equivalent Items

Hi everyone,
I’m looking for a loop combination to retrieve the equivalent item assigned to a specific component.
In my case, I’m looking for a "Manufacturer Equivalent Item" linked to a standard part.

The tricky part is determining whether it’s a "Manufacturer Item" or a "Physical Item" containing the Manufacturer Item—and how to access the Manufacturer Item information.
I can’t seem to extract this data from the "Data" section, or perhaps I just haven't found the right path yet.

I’ve attached the combination I’m currently using; maybe you’ll spot something.

Ultimately, I want to have the file title in my list.

If you have any tips, that would be great.
