Changing Line Width of a Trace in a Net without DRC Errors

Hi,

I would like to know a way to change the line width of a trace within a larger net without DRC errors.

I have a net with 100mil line width assigned to it. There are several traces branching off from this main 100mil line that I want only 8mil thick (e.g. pull-up resistors/decoupling caps). When I manually change the line width for these traces (and they are long traces), I get millions of L><W error markers on them. Is there a proper way to do this in OrCAD PCB Designer Standard 17.2 version (and I am new to it).

Any help would be greatly appreciated. Thanks.
