When you run this command, you purge the following types of roster data:
Roster Timebands
Roster Transactions
Roster Scenario Timebands
Roster Scenario Transactions
Purging Rosters
You should purge roster periods every time you open a new roster period.
If you have more than one roster period set up, for example fortnightly and monthly, you should purge only fortnightly roster periods when you open a fortnightly roster pay; and purge only monthly pays when you open a monthly roster.
Procedure
When the Closed Pays to Purge from Current window appears, click the check box for the roster pay periods that you want to purge.
