Altium Multi-Channel schematic net labels are not repeated

(1/2) > >>

aslan7:
I am using Altium Designer 20.2.5 and trying to build a hierarchical design. There are two schematics: top level and sub level, as shown in the following figure (named Top Level):

What I expected was that all the PWM net names in the sub-level schematic would change properly (PWM1, PWM2...PWM8), but the net names don't change, as shown in the following figure (named SubLevel). Each channel has the same net name.

ajb:
Do you get the correct connectivity on the PCB?  Altium will show compiled component designators for a multichannel design, but it won't show compiled net names as far as I've seen.  So it's not clear that anything is wrong here just from the schematic.

aslan7:
I need help what else to check in my project. In ProjectHierarchy.png, my project hierarchy seems okay as far as my understanding. In ComponentDesignators.png, component designators are changing properly; but net labels do not.

When I validate my project, I am encountering some errors as shown in Error.png. Also, in PCB side, there's no connection for LED anodes (PCB_Connections.png).

I really don't know if something's missed.

ajb:
It might be because you have a port called "PWM_MCU[1..8]" connected to a bus called "PWM[1..8]".  Try setting them to the exact same name.  Bus ports are a little weird and I think that may be necessary for them to connect properly. 

Or it could have something to do with how the PWM_MCU[1..8] port is connected to the next sheet up, can you show that?

aslan7:
I've tried many combinations of port/label naming -including same port and label name- but none of them worked.

Previously, the PWM_MCU[1..8] port was not connected anywhere. Now, I removed the port and added a connector and drew the bus; please check if any problem is seen.
