The EssAllowAccess system parameter impacts the message "Access to this page has not been approved".


One reason an employee might receive the following message restricting access to ESS is because their (admin > security > user) record has a value in the "inactivation date" field.  When the inactivation date is removed ESS access is allowed.




The program logic loads the inactivation date any time an employees status is changed to DE, LY, RT, or TR. 
 
Note that if there is a System Parameter created called EssAllowAccess and the parm value is set to Y.  Then the inactivation date is not set for status code changes to LY.
 
Following is an example of the EssAllowAccess system parameter.
