I am running into an issue where I either get no population of Country Made In, or I get an error.
It accepts this

But does not populate this

And does not accept this, which is apparently the correct way to do it:

Also worth noting here is it will not allow me to select "Distribution Center?" when trying to create the formula, despite the data clearly being there:

Even weirder is, that's the list, right? SYS06 has the same data. So I tried:
PARENT('SYS06 Location Details'.Distribution Center?) but got this:
So it won't let me use the list because the formula is invalid, but it won't let me use the module, because it has to be a list?
I tried using this instead, because both the G3 Location List and the SYS06 Location details have common dimensions, like "Code" however
'SYS06 Location Details'.Country[lookup: Supplied By], and'SYS07 Distribution Center Details'.Country[lookup: Supplied By]
result in:

And this is true for any column.
