I've had a request to record the date/time and user ID of the person who converts or creates a work order and tie this information to the WO.

I had this same problem with an xBase system that I was tasked with maintaining years ago.  The solution was fairly simple, assuming that TAS has a way to access DOS environmental variables.  At the time of login, create an environmental variable with the users initials or ID or whatever tag you want to use.  (We wrote a small program in C that polled Novell and Microsoft networks User IDs)  You could also create a global variable that could be referenced when needed.  Now create a line in the notes field with the user ID and a time/date stamp each time the work order (and a short description of change) is changed and saved.  It is not exactly a transaction tracking system, but it got the info needed for reference purposes.  Just an idea.

We have worked out a way using TAS 6 Evo to track DBA Login so that change tracking can be maintained and will be implementing it in various programs.  It will require the TAS 6 Evolution menu, the standard DBA menu can not do this.
