The coefficients are built-in that you can modify:

If you do not know the coefficients, simply use the default values from the material database. For any new materials, you may need to find them from literature, or "borrow" from similar materials, with possibly reasonable modifications if you can.

As for the job error, most likely the material properties are not complete, or improper. You can borrow the parameters and check if the new material works for example Si, before testing ITO material. Once it works, then try the ITO again with proper parameters. 

As for what is "proper", it is hard to justify here since this is material property, which is inherent from the material its self. It is better to know the material before simulation.
