BobWeaver Posted January 15, 2001 Share Posted January 15, 2001 Create a self-join relationship in your projects file using the project number for the key field. Self-join is described in the manual. You will need either a serial number or DateCreated field to determine the latest record. Then create a calculated field called cLatest: cLatest = Calculation[Max (Projects::SerialNo) = SerialNo] where "Projects" is the name of the self-join relationship, and SerialNo is the unique serial number or date. The value of cLatest will be 1 for the latest record of each project, and 0 for all others. Link to comment Share on other sites More sharing options...

timmy Posted January 16, 2001 Share Posted January 16, 2001 I have a database of projects. Each project has a project number. However, there is more than one record for each project number. How can I tag the most recent record of each project number as being "unique" or "most recent"?
