There is a note in the 'Add Attribute Rule' notes I have a question about:
"Note: Once you add attribute rules to a dataset, the minimum client version for the dataset is ArcGIS Pro 2.1. This means that the dataset will no longer be available for use in ArcMap."
If I add an attribute rule by right clicking a layer (or table) in my SDE (Design -> Add Attribute Rule) will I be unable to open any feature classes or tables from my SDE in arcmap or just that specific feature class or table?
