A current row of data within CONNECT displays the most up-to-date information available, or what is currently affecting a change to the data.
John Smith got married on September 12, 2007. Human Resources inserted a data row in his record that indicated a change of status from single to married, effective September 12, 2007. If you were to access John's record today, the current row would show September 12, 2007. Unless John has a status change in the future, September 12, 2007 will remain his current data row.
