If you want to run a report that includes such as all customers with just a couple of exclusions this month's tip will be of help to you.

In the example report below all customers are selected with the exception of ABB001 and BET001.  Firstly from the Personalise screen ensure the Advanced Terminology button is selected and the paging size is set to 999999.  


 To complete the exclusion hold the shift down and select the first customer number, scroll to the last customer and click that (whilst still holding the shift key down), then hold the control key down (rather than the shift key) and click those customer numbers you want to exclude.
