Manage Bean : invoiceBean Here, I following method is used to store data in specific object.

You're not clearing out the dialog before opening it.

Change

<p:commandButton value="Add Invoice" type="button"
    onclick="PF('addInvoice').show();" />

To

<p:commandButton value="Add Invoice" type="button"
    action="#{invoiceBean.createInvoice}" update="invoiceDialog"
    oncomplete="PF('addInvoice').show();" />

With

public void createInvoice() {
    hsnCode = null;
    quantity = null;
    rate = null;
    percentDiscount = null;
}

---

That said, the design of your model is broken. You're flattening and repeating the model's properties straight in the backing bean instead of using the model directly. Fix it by removing the hsnCode, quantity, rate and percentDiscount properties and then adding this:

private InvoiceProductsServicesDetail invoiceProductsServicesDetail;

public void createInvoice() {
    invoiceProductsServicesDetail = new InvoiceProductsServicesDetail();
}

With

<p:inputText value="#{invoiceBean.invoiceProductsServicesDetail.hsnCode}" ... />
<p:inputText value="#{invoiceBean.invoiceProductsServicesDetail.quantity}" ... />
...
