The system is designed for the Stage One Received Date to be overwritten by the Stage Two Request Date when it is received. However sometimes there is a lag with this updating (I have had an example where within the Request the field continued to show the Stage One Request Date for a little while even though within Workspace the field showed the correct Stage Two Date.

Although the Stage Two Received Date is the preferred date to record if we had to choose, it would be useful if both dates were retained within a field.
