Posted 2021-05-09

# max = max FACILITYID value in dataset. This can be calculated with a function
with arcpy.da.UpdateCursor('feature_class', ['FACILITYID'], "FACILITYID IS NULL") as cursor:
    for row in cursor:
        new_facilityid_number = max + 1 
        row[0] = str(new_facilityid_number)
        max = new_facilityid_number
        cursor.updateRow(row)
