I think I need to clarify my question. I want to look at the statement of cash flows using a filter for a specific set of classes. This works fine, except that the specific payment transactions do not have a class attached to them. I cannot see anywhere on the "Receive Payments" dialog box that would allow for a class to be assigned. As a result, these payments are not included on the Statement of Cash Flows when I filter for specific classes, because the actual payment itself is presumably "Unclassified". My company is already set on a cash basis.

So in an unfiltered Statement of Cash Flows, the invoices are included in the Net Income line, while open balances are counted against net cash in the Accounts Receivable line below. But when filtered for a class, the invoice for that class will show up in Net Income, but the payment is not classed, so the Accounts Receivable line shows all invoices as unpaid and reduces Net Cash by the total amount of invoices.

If I invoice a tenant in Class:PropertyX for $500 and they pay $400, an unfiltered Statement of Cash Flows shows:

Net Income: $500

Accounts Receivable: -$100

Net Cash: $400

If I filter the same report for Class:PropertyX, I get:

Net Income: $500

Accounts Receivable: -$500

Net Cash: $0

Which makes a Statement of Cash Flows filtered by Class sort of worthless. Am I doing something wrong here, or are Statements of Cash Flows not meant to be filtered by class?
