Find Assignment Rule that Created Revenue Contingency?

Hi,

Using AR in R12.1.3 (moving to 12.2.9 this fall, if that matters).

I have an invoice line where the revenue was deferred by a revenue contingency that was applied due to an assignment rule.

I know I can find information about the deferred revenue and contingency in AR_LINE_CONTS_ALL and AR_DEFERRED_LINES_ALL.

Neither of these are referring to a "rule" that would have created the record. Is there a way to query, for a given invoice line in AR_DEFERRED_LINES_ALL what rule caused the deferral to be applied?

Thanks.
