PRS

All transactions are treated as MaintainProvider transactions. The PRS does not know whether the provider is to be created or updated until it finds an existing provider based on the incoming data. If a provider already exists, the PRS continues to update the existing provider with the data in the message.Before actually updating the data, the PRS performs change detection. If the PRS determines that there is no change in the data it does nothing and returns a SUCCESS message. If the PRS does detect change, but no End Reason Code is supplied (as in the case of a add provider message), the PRS will return a failure indicating that no End Reason Code was supplied. If the user wanted to explicitly create a duplicate provider with exactly the same data, the Assertion Flag should be checked. This indicates to the PRS that, if the provider does exist, do not update the existing provider's data, but add a new provider. The PRS will create new provider and create a potential duplicate entry.
