In Goal Management, organizations are able to set and track two types of goals: individual goals, which are specific to an individual employee, and organizational goals, which are organization-wide goals that all employees should work towards. For example, an individual goal could be to increase sales by a certain percentage, while an organizational goal might be to reduce costs by a certain amount. Reference: Oracle HCM Business Process Foundations Associate Rel 1, Chapter 7 - Goals, page 32.

Extending a job offer is the process of formally offering a position to the applicant. This is typically done in writing, either by email or by sending a job offer letter. The purpose of extending a job offer is to provide the candidate with all the necessary information they need to make an informed decision about whether or not they will accept the position.

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.
