As we see more customers upgrading to GP 2013 R2 we noticed the following security roles and tasks are missing:
ESS EMPLOYEE MANAGER*
ESS PTE EMPLOYEE*
ESS PURCHASE REQUESTER*
This is noted in the Upgrade Instructions manual that you will need to add these on an upgraded install.
A new install will load them for you.
The SCRIPTS will create these missing security roles and tasks for you.
