ArcGIS Pro 2.7.1 and sde.
I have a question. I need to set up a unique identifier on text field to avoid repeat. For example, a staff entry an address information 1234 NW 103 AVE UNIT 123. I am unable to find enough information. I found a piece of information from ArcGIS documentation. please let me know what step by step is.
"If a single string field is used as the unique identifier, ArcGIS must map those unique values to an integer. This is done in ArcGIS anytime the system needs an Object ID attribute, such as when creating a map selection or opening the attribute table. ArcGIS adds an attribute called ESRI_OID and stores a unique integer value in it. This attribute is only part of the layer definition; the underlying database table is not altered."
