Some more queries on the Reporting|Debtors processing

1. What is the effect of checking the Reprint box when you generate statements using Send All?
    
2. By testing I know that if you have a selection of customers by name (ie from A to M) then pressing Send All will only do the statements for those customers.  Does the customer name selection have any effect on End Period processing?
    
3. What is the reason for being able to select customers by name (rather than say account type as you can on the reminders screen) - is it simply to limit the number of statements generated (because its easier to print smaller lost of statements) ?
    
4. Can you confirm that the logic for generating the amount of the closing balance transaction is 'sum all finalised transactions with dates after the previous opening balance transaction and prior to midnight on the period end date'.
    
5. Given the above logic, what happens to an invoice that is in progress (not finalised) at the time of period end processing.  When it is finalised does the invoice get a new date? (I checked the archetype and it has only a startTime, not an endTime.)  ie I am wondering how invoices that are initiated in one accounting period and finalised in the next are handled.
    
6. Are there any rules about which order you should do send-all and end-period ?
