Altium : Component contains Open Emitter Pin and Power Pins Objects

[raviani]

Hi, I'm a new user in Altium. I try to update PCB document file.PcbDoc and get the warning errors occured during compilation of the project. It seems some components is not connecting in the schematic. The error messages is component contains Open Emitter Pin and Power Pins Objects. Actually a red cross is shown when I try to connect the components. I am struggling with finding the solution. Thank you for your help.

A snapshot of your circuit would have helped. Generally when you are placing a wire in Altium, a red cross appears at the location where the wire can be connected/terminated. Failing that, deleted the transistor and place it again making sure all pins are terminated.
