Has anyone explored this tool that comes as part of iSeries Navigator? Our application has over a 150 physical files that have relationships but DB navigator doesn't recognize any of them as they don't have constraints added using Add PF Constraint command (ADDPFCST). Building a (pretty picture) map of the 'database' is the ultimate goal. Anyone know of a tool that can show this graphical representation similar to ERWin? Or a method of generating the details from the 400 to something ERWin can import? Trevor
