How To Override Buildtaxrequest Method Of Apinvoiceentryexternaltax Class

Hello everybody,

today I want to leave a short techy post on how to override method BuildTaxRequest of APInvoiceEntryExternalTax class.

public class APInvoiceEntryExternalTaxExt: PXGraphExtension<APInvoiceEntryExternalTax, APInvoiceEntry>
{
    [PXOverride]
    protected virtual GetTaxRequest BuildTaxRequest(APInvoice invoice, Func<APInvoice, GetTaxRequest> baseAction)
    {
        var result = baseAction(invoice);
        //Your code
 
        return result;
    }
}

Reason for such a behavior is a fact that class APInvoiceEntryExternalTax is graph extension for graph. That's why such a construction is needed.
