Extending SalesInvoiceDP class.

(0) ShareShare
ReportReport
Posted on by Johnny 6,480

Hello,

I have to add some new fields to tmp tables used in salesInvoiceDP class.

I wanted to assign values to new fields in newly created _Extension class of SalesInvoiceDP and wanted to use Chain of Command.

I wanted to modify "insertIntoSalesInvoiceHeaderFooterTmp" method with CoC, but it gave me error as insertIntoSalesInvoiceHeaderFooterTmp is a private method and can't be used within Coc.

Then I tried to copy pre event handler of that method, but I got an error:

"Pre or post event handlers can only be created on hookable methods. Hookable methods are non-abstract methods that are either public or have been attributed with Hookable(true)."

What would be a best option to correctly fill new fields in DP classes? In this case SalesInvoiceDP, insertIntoSalesInvoiceHeaderFooterTmp method?

Thanks.

    Update:

    I'm going to use CoC on "insertInvoiceHeaderInformation" method, which calls "insertIntoSalesInvoiceHeaderFooterTmp".

    My method looks as below:

    public void insertInvoiceHeaderInformation(CustInvoiceJour _custInvoiceJour, CompanyInfo _companyInfo)
{
    this.salesInvoiceHeaderFooterTmp.xxxPaymTermsDays = PaymTerm::find(_custInvoiceJour.Payment).NumOfDays;

    next insertInvoiceHeaderInformation(_custInvoiceJour, _companyInfo);
}
    Here I'm getting compiler error: Invalid token '='.
    xxxPaymTermsDays, which is new field added to salesInvoiceHeaderFooterTmp extension table is same edt as NumOfDays.

    What am I doing wrong here?
    Thanks.

    The Invalid token '='. compile error occurs in Visual Studio when the table field of the extended class is assigned directly:

        public void insertInvoiceHeaderInformation(CustInvoiceJour _custInvoiceJour, CompanyInfo _companyInfo)
    {
        this.salesInvoiceHeaderFooterTmp.BuyerName = 'The buyer name'; // < Invalid token '='

        next insertInvoiceHeaderInformation(_custInvoiceJour, _companyInfo);
    }

    However, there is no compile error when the assignment is done using a local variable of the temporary table:

        public void insertInvoiceHeaderInformation(CustInvoiceJour _custInvoiceJour, CompanyInfo _companyInfo)
    {
        SalesInvoiceHeaderFooterTmp salesInvoiceHeaderFooterTmpLocal = this.salesInvoiceHeaderFooterTmp;

        salesInvoiceHeaderFooterTmpLocal.BuyerName = 'The buyer name';

        next insertInvoiceHeaderInformation(_custInvoiceJour, _companyInfo);
    }
