R12 AR process flow

 I would like to find documentation on what the Receivables process flow is in R12.  In 11i, you start with create customers, enter transactions, apply receipts, process adjustments, print documents, perform collections, close period.

I'm guessing R12 Receivables process flow is the same, but with SLA thrown in the mix, I'm feeling a little lost and just want to make sure I understand the module process flow correctly as I investogate the module
