Operators not available for certain field types

[Alfredo Garza1]

When creating a standard report in ServiceNow, I can select "IS ONE OF" or "IS NOT ONE OF" for a choice field (ex: Priority). But when I try to do the same for a string field (ex: Assignment Group) I get the "IS ONE OF" option but not the "IS NOT ONE OF". Is this by design or am I overlooking something?

This is by design. Different field types have different operators. See full list here

So do you know why they allow the option of "IS ONE OF" if they don't offer the opposite for it?

No idea!

So you reply with insight on why "is not one of" is not there for the String field, but you can't say why "is one of" is there despite it saying it should not be there for that field type? 🤔

Do you understand why that isn't helpful to the question?
