Online CUs must contact a Client Service Representative to make these changes to your configuration.  (You can, however, view the configuration using Tool #961 View Reg E Triggers for Statements.)  As long as you let us know before the last day of a month, we can make the changes to your configuration before statements are generated on the 1st. 

(Self Processors can change these settings via OPER Tool #5434 Member Statement Config.)
