Hi @Irene M ,
The portal actually pulls that label straight from the backend dictionary. Since you only want to change it for Incidents without affecting other task types, the best way to do it is via a Dictionary Override.
Just follow these steps:
Go to System Definition > Dictionary and search for the comments field on the task table.
Open the record and scroll down to the Dictionary Overrides related list.
Create a new override for the incident table (or open the existing one if it's already there).
Check the Override label box and type the new name you want.
I haven't fully tested this specific scenario on my end recently, but it should do the trick. Just keep in mind this will also update the label on the native UI incident form, which keeps everything aligned. Hope this helps!
Best regards,
Brandão.
