You didn't post a very detailed question so I hope this will help you a bit:

A problem you can have is that the field already exists in a Class that you extend. In this case the field would already exist in Class B.

Say:

public class A extends B {
    private BigDecimal netAmountTcy;
    private BigDecimal netAmountPcy;   
    private BigDecimal priceTo;  
    private String segment;

    private BigDecimal taxAmountTcy;
    private BigDecimal taxAmountPcy;   
    private BigDecimal tradeFeesTcy;
    private BigDecimal tradeFeesPcy;

// getter and setter for the above fields

}

where class B is something like (and maybe more duplicates of course):

public class B {
    private BigDecimal netAmountPcy;   
// getter and setter for the above fields

}

Just remove the field "netAmountPcy" Class A and you will still have the field (because it extends the class).
