NetSuite Integration with Tableau

I have successfully integrated NetSuite with Tableau, I can see customer, accounts records, but I am not able to see the transactions although I have given permission in NetSuite in access role. Secondly, I am getting an error while fetching employee record in Tableau, whereas customer record is fetched successfully. This is the error while fetching employee:
