Hi, I am taking Garmin Data from small planes, and exporting that data to a shapefile. From that shapefile I am exporting the attributes to excel. In excel I am retaining all the fields from the shapefile, and doing calulations based on those fields. After I have completed my calculations, and try to join the new table with the shapefile it says my table has no OIDs, it does the same thing if I do this process from a feature class. Is there anyway to fix this? So I can join my tables?
