Example
In the first example, the attribute a_ Attr1 is assigned a value of 2. The second example assigns the value of a_ PO_No to the attribute a_ Invoice_No . Number three assigns the descriptor Red to the attribute a_ Color . And the last example assigns the product of 5 and the value of Base to the attribute a_ Size.

2) a_Invoice_No = a_PO_No
3) a_Color = Red
4) a_Size = 5 * Base
