Payables: Reversing swept transactions or sweeping future period transactions?

As I work on the Close for Receivables tonight, the document on MOS "How do you unsweep/reverse the sweep for transactions swept by the Unaccounted Transaction Sweep Program? How do you sweep transactions entered in a future period that was mistakenly opened to a previous period?" from article ID 2094016.1 seems especially penitent!  Check this out for the answers AND participate in the Payables Community by voting on the associated Enhancement Request!
