To calculate risk, RBI, PRD, and Piping Analyses require values in certain fields in associated RBI families. If you try to calculate an RBI Analysis and any required fields do not contain values, the analysis will not be calculated. Some fields are conditionally required, and these conditions are described in the Notes column in the table.
In order to calculate an RBI Analysis, values may be required in certain fields in the following families:

Several fields in RBI families are required in order to calculate RBI PRD Analyses. If you try to calculate an RBI PRD Analysis and any required fields do not contain values, the analysis will not be calculated, and the Calculation Status dialog box will appear, displaying a list of the required fields that do not contain values. The required fields differ depending upon whether the RBI PRD Analysis contains a Leak Criticality Degradation Mech Evaluation record or an Over Pressure Criticality Degradation Mech Evaluation record.
The following lists describe the fields that are required in order to calculate RBI PRD Analyses that meet the following criteria:
They contain an Over Pressure Criticality Degradation Mech Evaluation record (i.e., a record belonging to the Criticality Over Pressure Deg. Mech. Eval. family).
They contain a Leak Criticality Degradation Mech Evaluation record (i.e., a record belonging to the Criticality Leak Deg. Mech. Eval. family).
The lists are categorized by the family to which the required fields belong.

Consequence for Protected Assets
Note: The Consequence for Protected Assets field is required only when the pressure relief device protects equipment.

Note: If the pressure relief device protects RBI Components, the Operating Pressure field is populated automatically from the Operating Pressure field in the driving Criticality Calculator RBI Components record. If, however, the pressure relief device protects equipment, you must type a value in this field manually.

Note: The Driving Component field must contain a value if the pressure relief device protects RBI Components.
Damage Factor Class
Note: The Damage Factor Class field must contain a value if the pressure relief device protects equipment.

They do not contain a Leak Criticality Degradation Mech Evaluation record (i.e., a record belonging to the Criticality Leak Deg. Mech. Eval. family).
The lists are categorized by the family to which the required fields belong.

If, however, the pressure relief device protects equipment, you must type a value in this field manually.
Operating Temperature
Protected Equipment Type
Note: If the pressure relief device protects RBI Components, the Protected Equipment Type field is populated automatically based upon the value in the Criticality Item Type field in the driving Criticality Calculator RBI Components record. If, however, the pressure relief device protects equipment, you must type a value in this field manually.
