If you want to control which of the fields on a form are editable, you can use the property allowEdit of the datasource fields. If you have large tables containing a lot of fields, this could be a time-consuming process.

So, if you have a form, where the user should only be able to edit one field - in particular case a field from table salesLine -, you could use the following code-example which should be included in the init-method of the datasource. The snippet disallows editing for all fields exept for one field. 

Tested in AX 3.0
 

The following method contains some snippets that can be used to call various functions/methods of the calling object (form).

If you change element.args() to e.g. _args and pass the arguments to the method, you can use the code within a class as well.

void workWithCallingRecord()
{
    common          common;
    object          object;
    formDataSource  formDataSource;
    formRun         formRun;
    inventDim       inventDim;
    salesTable      salesTable;
    int             i;
    ;
    // Call method from calling record
    if( element.args() &&
        element.args().record() )
    {
        common = element.args().record();
        if(common.isFormDataSource())
        {
            info(tableId2Name(common.TableId));
            if(formDataSourceHasMethod(common.dataSource(), identifierStr("someMethod")))
            {
                object = common.dataSource();
                object.someMethod();
            }

    // Call method from calling form
    if(element.args() && element.args().caller() && element.args().caller().handle() == className2Id('formRun'))

        if(common.TableId == tableNum(salesTable))
        {
            info(common.(fieldNum(salesTable, salesId)));
        }

            {
                inventDim = formDataSource.cursor();
                break;
            }
        }
        if(inventDim)
        {

            {

            // Update data
            salesTable.PurchOrderFormNum = "Some value";
            salesTable.update();
        }
    }

    // Refresh calling datasource
    if( element.args() &&

If you try to change the AllowDuplicates-Property of a table index from No to Yes, the following error message may occur:

Illegal property value

In this case, presumably, the affected index is registered as PrimaryIndex or ClusteredIndex of the table.

Using the following code you can easily print sales invoice through code. With slight modifications to the code, this is also true for all other sales- and purchase-sided documents.

Short example in AX 2009

static void PrintSalesInvoice(Args _args)
{
   custInvoiceJour     custInvoiceJour;
   SalesFormLetter     salesFormLetter = SalesFormLetter::construct(DocumentStatus::Invoice, false);
   PrintJobSettings    printJobSettings = new PrintJobSettings();
   Args                args = new Args();
   boolean             prompt = true;
   boolean             printIt = true;
   ;

   if (prompt)
   {
       // Dialog
       printIt = printJobSettings.printerSettings('SysPrintForm');
   }
   else
   {
       // Printjobsettings
       printJobSettings.setTarget(PrintMedium::File);
       printJobSettings.format(PrintFormat::PDF);
       printJobSettings.fileName(@'c:	empmyfile.pdf');
   }

   if (!printIt)
   {
       return; 
   }

   salesFormLetter.updatePrinterSettingsFormLetter(printJobSettings.packPrintJobSettings());

   select firstOnly custInvoiceJour
       where custInvoiceJour.salesid == '100001';

   args.record(custInvoiceJour);
   args.caller(salesFormLetter);

   new MenuFunction(menuitemoutputstr(SalesInvoice), MenuItemType::Output).run(args);
}
