Hi Sharath,
When you get error, below in job log you can see completed with errors. Just double click it.
Through SYSTEM user, admin will give privileges to your user. If you are practicing HANA then if you have the access to do so, then you can do by yourself.
If you are in project then ask your admin to give privileges.
By the way what are all the privileges you have? It helps to know what additional privileges required under each category
