180659: Field: <value> will be added to feature class <value> as [Nullable] instead of [Non-Nullable] due to existing data.
Description
The feature class contains existing data, which prevented non-nullable fields from being added. The field will be added as nullable instead.
Solution
Do one of the following:
Create a new version of the feature class, run the upgrade tool, and append the data from the original feature class to the updated feature class.
Take no action. The nullable properties of fields do not affect how data is used in the Indoors apps.
