1. The Open Period Mass Update page displays.  In the Selection Criteria section, in the PeopleSoft Product field, enter "GL".  
   • Note: you can choose one module at a time and change each module individually, but if you choose GL you can update all the modules at one time.
2. In the Calendar field choose "01";  this represents the monthly calendar.
3. In the Unit field enter appropriate unit number.
4. In the Ledger Group field enter the appropriate ledger group, or % for all ledger groups.
5. Select Search.
6. In the Update Selected Rows section you are choosing the year and the periods you want OPEN.  
   • Note: you are not CLOSING months you are telling the system what months to leave open.
7. Enter From Year, From Period, To Year, and To Period;  if you are closing regular months you will not be selecting Def Adj Year or Def Adj Period.
8. In the Open Period(s) section select all ledger groups.
9. Select Apply.  
10. You are now choosing the modules you want to update with this open period.  In the section “Migrate Selected to Subsystems”, identify the sub-modules to adjust with the mass update to open period.  (In our example we chose AP.  In most cases if you are doing Mass Update you will be choosing more or all).
11. Select Migrate.
12. Select Save.
13. Notice in the Open Period(s) section the column “First Open” has changed.  This represents the OPEN date.  Anything before this will be closed.
14. Look at the “Last Open” column.  This is the last date this is open.
15. It should be noted that the mass open may not be the most widely chosen way to open and close module.  If modules are to be closed one at a time it may be more appropriate to use the “Open Period Update”.  It is located along the same path as Open Periods Mass Update.

16. To review the modules after you have updated the open dates you can look at the “Open Periods” in the page above or navigate to:
    • NavBar > Navigator > Set up Financials/Supply Chain > Business Unit Related> General Ledger> Open Periods> Open Period Display.  
17. Enter the module you wish to review, and the appropriate Business Unit and Ledger Group “Actuals”.
18. Select Search.  If you leave the field “PeopleSoft Product” blank it will bring back a search criteria for all modules.

19. In the example below, AP is open with the first open date of 3/1/2018 through 6/30/18. February 28th, 2018 and before are closed periods.
