How to post multiple Free Text Invoices using x++ D365 FO

These days one of the most common requirements is to post multiple Customer Invoices in a single click.


Here is an example :-

[FormControlEventHandler(formControlStr(CustFreeInvoice, BulkPost), FormControlEventType::Clicked)]
public static void BulkPost_OnClicked(FormControl sender, FormControlEventArgs e)
{

    FormDataSource                fds;
    MultiSelectionHelper         selectionHelper = MultiSelectionHelper::construct();
    Set                                       selectedRecords = new Set(Types::Record);
    CustInvoiceTable                custInvoiceTable;
    CustPostInvoice                  custPostInvoice;
     
        fds = sender.formRun().dataSource('CustInvoiceTable');

        custInvoiceTable = fds.cursor();

        selectionHelper.parmDataSource(fds);
        custInvoiceTable  = selectionHelper.getFirst();

        if (custInvoiceTable.RecId)
        {
            while (custInvoiceTable)
            {
                selectedRecords.add(custInvoiceTable);
                custPostInvoice = new CustPostInvoice(custInvoiceTable);
                custPostInvoice.run();
                custInvoiceTable = selectionHelper.getNext();
            }
        }

        fds.research();
        fds.reread();
        fds.refresh();

        Box::info('Invoice Posting Completed Successfully');
}
