Filters in System Architect and IBM Rational DOORS
System Architect provides IBM Rational DOORS filter from the Explorer menu. Only one filter may be active at a time. Once you set qualifications in one filter the other filters become disabled. The Reset Filters option allows you to clear all filtering without having to go to the specific filtering dialog.
The IBM Rational DOORS Filters dialog has three qualifications:
Not sent and not to be sent to IBM Rational DOORS
Sent to IBM Rational DOORS
To be sent to IBM Rational DOORS
