I have re-annotated PCBs and back-annotated the schematics countless times before and never saw this problem.
I first make sure that my PCB and my schematic are synchronized and up-to-date. In the PCB I go to
Tools -> Re-Annotate. I select my direction, set my comparison threshold, etc and click "OK". The board re-annotates as expected. I save the board and the project. However, once I go back into my schematic and click
Tools -> Annotation -> Back Annotate Schematics and select the .WAS file that was just generated, I get the following error:
There are only 294 components in the design. I cannot seem to track down the cause or solution to this problem. What might the issue be?
Once again, I am using the same process I always use and it has always worked in the past. I have even tried resetting all component designators in the schematic, annotating the PCB, and back-annotating to the schematic but that does not work either.
I am using Altium 17.1.5.
