Query with the date that a sales order was cancelled

My Daily Bookings report is picking up the daily sales and daily cancelled sales orders.  We have an issue when a sales order is created in month one, but cancelled in month 2.  The bookings report in month one should show the sale, but in month 2 show the cancellation (with negative numbers)

I am having difficulty querying the date that a sales order was cancelled using ADOC and ADO1 etc tables.  I am trying to select:

Select

Sale Order number,

Status,

Posting Date,

Date cancelled

From

  ORDR

  AD01

Where

Posting Date between '[%1]' and '[%2]'

OR

Date cancelled between '[%1]' and '[%2]'

If the cancellation date is with the same period as the posting date, then displaying only the cancellation date is fine (or both if need be)

thanks,

Tony
