Thanks, that helps a lot. (I assume that when you modified the part, you told the system that the vss and vdd pins were power in types)
The problem is not so much a pin error but a DRC warning. You have a few options depending on your design. You could insert a dummy component and connect the pins via that to + or 0v as required. Or connect to a couple of jumpers. Not really ideal in most cases, but if yo8u use jumpers in your design they can perform that function You could as Alain suggested edit the pin to be passive, that works but is not ideal. Thirdly you could simply change the drc rules for that type of connection. Click on the drc button, and then select options. On the right hand side, 8 down (power out) then three across (follow that up and you will hit bidi) at 8,3 you will see that it is set to a yellow square with a W in it, (warning) if you change that to green that will tell drc that you want it to allow power connections to bidi pins and you error will go away. The errors you are getting are warnings, so they do serve a useful purpose. You could simply ignore them and carry on. Remember to be careful if you change drc rules.
