It appears to be a bug. Depending on what you are trying to do there may be an alternative way of doing this. Are the property names/values unique?
Yes, they are unique. I have tons of pins with the same prefix in both, pin name and number, and I want to copy them all and replace the prefix.
I can export pins, replace pin number in a spreadsheet editor and import pins again. But than I have to rearrange the pins agian. -> not a good solution
I have also considered to work with multiple slots and reuse the same symbol in the part (which would be the most elegant solution). But then the automatic pin mapping is not working and up to know I not found a way to import the pin mapping from a spreadsheed. -> not a good solution
The simplest solution would be to use Add Properties. Select all the pins you want to change and reset the values with Add Properties configured to do so, in your example you'd set the Type to Pin and select whichever pin property you are changing, then Prefix=ABC Value=1 Delta=0 Suffix=_abc and click Apply.
Thanks for reply. Unfortunately this was not solving my issue because in my case the suffix was different all the time: ABC0_abc, ABC0_def, ABC0_ghi. Seems I described the problem not exactly enough. I now changed them manually.
