I have made an MDB Access Connection by linking the Excel file with the Access one, but when I looked at the result in ArcMap the feature class table does not have an Object ID on it. I tried to export the file in shapefile in order to get Object ID on it.
How can we keep the connection with the MDB Access connection with the new feature class in order to update the data directly from Excel table to be displayed and updated directly on ArcMap?
