When opened by clicking the Add New button on the Employee Accrual Balances page, the Accrual Definition Lookup window displays only those accruals that are assigned to the employee's pay group and that have not yet been added to the Employee Accrual Balances view for the selected employee. If no accruals are listed in the lookup window, all of the accruals available to the employee have already been added to the Employee Accrual Balances page. If no accruals appear on either the lookup window or the Employee Accrual Balances page, no accruals have been configured for the employee's pay group.
If some employees do not appear in the Employee ID Lookup window, you may need to edit your active employee filter or select a different filter. The employee filter allows you to narrow the set of employees whose records are displayed to you. Note, however, that you can only add to an employee filter those employees who belong to security groups to which you have access. If an employee belongs to a security group to which you have not been granted access, you cannot add him/her to your employee filters or view accrual or accumulator balances for the employee.
No. By default, an accrual or accumulator is added to the respective balance page when an employee first has a nonzero balance for that accrual or accumulator. If the balance later returns to zero, the accrual still remains on the page, so that you can easily access detailed information about the history of transactions associated with the accrual or accumulator.
The accumulator is probably configured to purge all balances on a regular basis, perhaps at the end of a calendar or fiscal year. Check the Employee Accumulator Balance Transactions page to see exactly what happened.
