Setting up plan priorities for capital planning requests is an optional step and is only required if you use the capital planning requests priority field to determine the plan priority, in which case it will save you from entering a priority for each individual capital planning request that you include in the investment plan.
To use the capital planning request priority, enter a value in the Weight field for each record of the Entity CPPR (Capital Planning Request Priority) on the System Codes screen of EAM. The higher the Weight, the higher the plan priority when optimizing the investment planning.
