Once an employee makes their benefit election, rates will be passed to payroll.

Once an employee makes their benefit election, the communicated amount from the benefits enrollment process is sent to payroll. This communicated amount is the rate associated with the employee's benefit election and is used to calculate the deductions for the benefit. This rate is sent to payroll along with the relevant information about the employee's benefit election, so that the payroll system can accurately calculate the deductions for the benefit.

According to Oracle HCM documentation1, communicated amount is the amount that the participant is told to expect for their contribution or distribution. It may be different from the defined amount, which is the amount that is defined for the rate2.

According to Oracle Support3, communicated rate is defined as per pay period with element frequency rules and it should be calculated properly in Benefits Self Service > Rates > Communicated Amount.
