Set Financial Dimensions by X++ code in AX 2012/Setting one Dimension value in the combination

    /// <summary>
    /// replace specific financial dimension value in DefaultDimension based on the LedgerParameters setup
    /// </summary>
    /// <param name = "_defaultDimensionFrom">DefaultDimension recId the value should be taken from</param>

Conversion from UTCDateTime to Date or Time in AX

Here is an example of correct conversion between UTCDateTime value and Date and Time value which is associated with user preferred time zone:
public static void testDateTimeConversion()
{
    utcDateTime dateTime;
    date dateInUserTimeZone;
    TimeOfDay timeInUserTimeZone;

    dateTime = DateTimeUtil::utcNow();

    dateInUserTimeZone = DateTimeUtil::date(DateTimeUtil::applyTimeZoneOffset(dateTime, DateTimeUtil::getUserPreferredTimeZone()));
    timeInUserTimeZone = DateTimeUtil::time(DateTimeUtil::applyTimeZoneOffset(dateTime, DateTimeUtil::getUserPreferredTimeZone()));

    dateTime = DateTimeUtil::newDateTime(dateInUserTimeZone, timeInUserTimeZone, DateTimeUtil::getUserPreferredTimeZone());
}

UserConnection in D365fo

Its used when we need to commit our transaction wehen standared code doesn't Commit.
example :SalesQuotationEditLinesForm_Sales_Send > checkSales() , COC and try to write 
custom insert or update operation here while validation is failed our transactions doesn't commit

static void KlForRecordInserted(Args _args)
{
    UserConnection userConnection;
    CustTable custTable;
    ;
   
    ttsbegin;
   
    userConnection = new userConnection();
   
    custTable.clear();
    custTable.initValue();
    custTable.AccountNum = "000020";
    custTable.Name = "My Test Customer";
    custTable.setConnection(userConnection); // set userconnection
    custTable.insert();
   
    throw error("An error that causes a rollback");
    ttscommit;
}

Access public variables in extension class using chain of command

When you wrap a method, you can also access public and protected methods
and variables of the base class.
CustInvoiceJour is a base class variable hence you will be able to access it. Eg.

[ExtensionOf(classStr(SalesConfirmJournalCreate))]
Final class SalesConfirmJournalCreate_Extension
{
protected void createJournalHeader()
{
next createJournalHeader();
//It's as simple as this:
custConfirmJour.SalesBalance = 0;
}
if gets an error, It's an old bug with variable names. Declare new one and use it:
protected void createJournalHeader()
{
next createJournalHeader();
CustConfirmJour custConfirmJourLocal =
custConfirmJour;
custConfirmJourLocal.MyField = 'blah-blah';
}
}
