QUESTION:

In ARCS, I have created an attribute with a calculation that takes the current period's balance and subtracts the balance from the prior period. If this balance is greater than $X, I want to require the preparer to submit a comment in another custom attribute.

With that said, is if there a way to only apply this to periods that are tagged as quarterly? So for example, if quarters ended in March, June, September, and December, it would only apply in September and would look to June to get the prior balance.
