R12.1.3 : Is there a way to automate the Period End Process for AP, PO, INV, FA, GL?

Hello,

R12.1.3 : Is there a way to automate the Period End Process for AP, PO, INV, FA, GL?  Or at least is there a way automate the Open/Close Periods for AP, PO, FA, GL ?    (  I know there is a program for INV. And also know that we can schedule Open Period for GL. But don't know for other modules)
