Bumping this issue as it seems to be an inconsistency in the product design and should be addressed one way or another.
Here’s a look at the schema for the two scenarios.
Using two tables, the schema does not cause a circular reference
However, I cannot achieve the same thing when the two tables are joined.
The red link is the one I wish to establish, but which caused a circular reference that does not make sense to me.
Is there a fundamental reason that Tables 1 & 2 are fine, but Table 3 (as I wish it to be) is not?
