AP report related queries

Hi All,

I am looking for some AP report to suit customer requirements, as below. Any help would be much appreciated:

1) When I try to give a date range in Advanced Query on "Open Order" application (P4310|ZJDE0006), iI can't put a date in as I get options like "+/- days from today". Why is it like that?

2) Is there a standard report to see list of all suppliers where Payee # <> Supplier #?

3) Is there a report which presents summarized view of R04424. Looking for these specific columns:

-- Supplier #

-- Supplier Name

-- Total Payments made for a period

-- No of vouchers paid
