Don't Copy 'n Paste Invoice Discounts

Hey all,

I have a situation with a document discount that when an Invoice is Copy ‘n Pasted it creates a copy of the discount.  I read this article, which is helpful, but I feel I’m missing something because nothing I’ve tried has worked.

I’ve set a PXCopyPasteHiddenView in a PXGraphExtension<ARInvoiceEntry> class:

[PXCopyPasteHiddenView]        

public PXSelectJoin<ARInvoiceDiscountDetail, InnerJoin<ARInvoice, On<ARInvoice.docType, Equal<ARInvoiceDiscountDetail.docType>, And<ARInvoice.refNbr, Equal<ARInvoiceDiscountDetail.refNbr>>>» Discounts;

I’m wondering if my PXSelect/PXSelectJoin is incorrect and if so what should it be?

Thanks all!
