Inputting yield strength data for an FEA using an added material

Whilst using COSMOS to carry out an FEA on a product part Iamcurrently in the development of, I tried to use amaterialwhich I had input onto the database.  I have enteredall ofthe physical properties to my requirements, but a message isshownin COSMOS which states that the 'yield strength' is notknown. I am unsure on where I can input this data and as aresult,have not been able to carry out the FEA.

Would be really greatful if someone could point me in therightdirection!
