I am a new user to ArcGIS Desktop 10.7. I imported data table from Excel 97-2003 format in the Table of Content. Then with XY recognition the layer was created with the defined coordinate system. The layer shows all the attributes but in the attribute table "Add Field" option does not show up. Also 'delete field', 'Calculate Geometry' and 2 other options don't activate. I tried to export the layer file to a shapefile and after the shapefile is created it does not show any attribute table.
Could anyone suggest a way to address this issue?
All I need to do is add field.
