Risk version list entity

The RIRiskVersionList entity helps manage multiple versions of a single reinsurable risk on a policy period. An RIRiskVersionList holds all the RIRisk instances for a single reinsurable risk, in an array called AllVersions. RIRisk instances have a foreign key called VersionList that links them back to the RIRiskVersionList instance that holds them. An RIRiskVersionList has the same value for its RiskNumber property as the RIRisk instances that it manages.

An RIRisk instance relates to its policy period through the RIRiskVersionList instance that manages it. An RIRiskVersionList has a foreign key to its policy period, called PolicyPeriod. A PolicyPeriod instance has a derived array of its reinsurable risks, called AllRIRisks. If a PolicyPeriod has any related RIRiskVersionList instances in its AllRIRisks array, its ValidReinsurance property is true.

Properties of risk version lists

The RIRiskVersionList entity has a number of properties. The properties related to the reinsurance plugins and web service are described in the following table.

Property	Description
`RiskNumber`	Unique identifier of a reinsurable risk.
`AllVersions`	Array of `RIRisk` instances that represent different versions of the same reinsurable risk.
`AttachmentInclusions`	PolicyCenter creates an `RIAttachmentInclusion` if the inclusion status of the attachment differs from the default, `Included`. Therefore, only attachments that are excluded or have special acceptance have an attachment inclusion row. When you exclude an attachment, PolicyCenter creates an `RIAttachmentInclusion` with the status set to `Excluded`.
`PolicyPeriod`	Policy period to which all versions of a reinsurable risk provide reinsurance coverage. Each version covers a different effective date range that does not overlap with the others. Only of one version is active at a time, though sometimes none are active.

Methods on risk version lists

The RIRiskVersionList entity has a number of methods. The methods related to the reinsurance plugins and web service are described in the following table.

Method	Description
`addToAttachmentInclusions`	Adds an `RIRisk` to the array of `RIAttachmentInclusion` instances on this `RIRiskVersionList`. The array name is `AttachmentInclusions`. An `RIAttachmentInclusion` relates an `RIRisk` on a policy period to a reinsurance agreement.
`addVersion`	Adds an `RIRisk` to the array of `RIRisks` on this `RIRiskVersionList`. The array name is `AllVersions`.
`endDate`	Splits the active `RIRisk` by doing all of the following operations. Sets `ExpirationDate` to today on the current `RIRisk`. Creates a new `RIRisk` instance with the same `RiskNumber` as the original. Sets the `EffectiveDate` on the new instance to today. Replaces all remaining fields except `ExpirationDate` from the original. Adds the new instance to the same `RIRiskVersionList` as the original.
`getRIRisk`	Gets the `RIRisk` that is active today.
`getVersionAsOfDate`	Gets the `RIRisk` that is active for a specified date.
`removeFromAttachmentInclusions`	Removes an `RIRisk` from the array of `RIAttachmentInclusion` instances on this `RIRiskVersionList`. The array name is `AttachmentInclusions`. An `RIAttachmentInclusion` relates an `RIRisk` on a policy period to a reinsurance agreement.
