If you are sending Statements out through all 3 methods, you will process Statements 3 times. Process them once each for Print, Fax and E-mail (separate buttons on Statement selection screen).

If each customer is set up to use only 1 method (ie. there is a check mark on Print but not E-mail or Fax), this will work properly. Be aware that if a Customer has 2 options with check marks, they will receive their Statement twice. If the Customers are not set up correctly, you could work around this by using Report Group or another field to group all of the people together who will use the same delivery method.
