On Saturday, July 4, 2009, the Common Working File (CWF) Hosts will be conducting a history purge. Due to the anticipated duration of this activity and to ensure the completion of weekly processing and scheduled data center maintenance, there will be a CWF dark day on July 4, 2009.
On this CWF dark day, the Health Insurance Master Record (HIMR), which is usually available until 12 p.m. on Saturdays, will not be accessible. HIMR contains information on the beneficiary's current entitlement and utilization status. This database is updated via claim submission through the host sites for utilization and via information provided by the Master Beneficiary Record (from Social Security Administration (SSA)) for entitlement.
All files received from satellites for Friday’s (July 3, 2009) cycle will be completed prior to bringing CWF production down. If for any reason satellite files are received late Saturday morning, they will be processed by CWF after the history purge has been completed.
