Sorry Randy, I may have misstated what I thought the solution was...I didn't mean to convey that no rule was needed. In all the examples I've seen, I've just seen transfer modes & closure rules used when a lot more was being done in the applicable TC dataset than a static SM snapshot.
I'd thought that since the %bl_ properties were available directly off the displayed SM BOM, that Teamcenter could "find" them without a rule to point at them specifically...if I'm wrong, I wouldn't be surprised. I'll try moving all of the %bl_ properties to their own line, per your suggestion.
If that doesn't work, do you know what rule would need to be applied in the rules table to point Teamcenter to the %bl_ properties I'm wanting to export?
