Banked hours reservations are banked hours that are earned in the future and can be used by an employee to request MORE hours than they have but WILL have at the date of the request.

For example, the normal processing of banked hours works like this

• An employee has 0hrs vacation
• On the 2^nd of each they accrue 20hrs
• By the 10^th the employee has used all 20hrs, from the 11^th-1^st they have no more hours to take

To enable the setting to allow the employee to take more,

• Go to MANAGE MY BUSINESS
• Go to MANAGE BANKED AND EARNED HOURS TYPES
• Select the banked hour type, click EDIT
• Enable this

  

With this enabled, in the above scenario

• An employee has 0hrs vacation
• On the 2^nd of each they accrue 20hrs
• By the 10^th the employee has used all 20hrs, from the 11^th-1^st they can request more hours pulling from their future reservation of upcoming accrued hours
