I have a yes/no option box, however, someone accidentally made a selection and I cannot seem to find where to set the field to Null. I've tried in dataverse but cannot set it to no selection (null = neither yes or no).
by standard UI you can't set back to null (empty).
Alternatives are a PCF control to handle null for boolean fields, a classic workflow (where you clear the value of this field) or set the value null by code
Hi,
If you want to allow user to set null we should use optionset field instead of Boolean type .
Now for your requirement you can create on-demand workflow to clear bool field value and run your workflow on the records where you want to set null
