Find below a short example, how to add object nodes to a shared project through code.

The so modified Project will look like this:

SysDictEnum SysDictEnum = new SysDictEnum(enumNum(SalesStatus));
int i;

for (i=0;i<SysDictEnum.values();i++)
{
    info(SysDictEnum.index2Label(i));
}

If the follwoing error occurs, when opening or synchronizing a - mostly new created - table

Cannot select a record in DMOTable (DMOTable). The SQL database has issued an error.

the reason could be, that the table contains a field, whose name is a "reserved word" from the database, For example, you cannot use Primary as field Name.

Find below some code-examples, how to Access external databases from Dynamics AX.

The examples are based on the following entry in MSDN:
How to: Connect to an External Database from X++ Code [AX 2012]
 

Read access (SELECT)

// X++, Main method in a class.
static public void Main(Args _args)
{
    LoginProperty loginProperty;
    OdbcConnection odbcConnection;
    Statement statement;
    ResultSet resultSet;
    str sql, criteria;
    SqlStatementExecutePermission perm;
    ;

    // Set the information on the ODBC.
    loginProperty = new LoginProperty();
    loginProperty.setDSN("ExternalDB_32bit");
    loginProperty.setDatabase("ExternalDatabaseName");

    //Create a connection to external database.
    odbcConnection = new OdbcConnection(loginProperty);

    if (odbcConnection)
    {
        sql = "SELECT * FROM items;";

        //Assert permission for executing the sql string.
        perm = new SqlStatementExecutePermission(sql);
        perm.assert();

        //Prepare the sql statement.
        statement = odbcConnection.createStatement();
        resultSet = statement.executeQuery(sql);

        //Cause the sql statement to run,
        //then loop through each row in the result.
        while (resultSet.next())
        {
            //It is not possible to get field 3 and then 1.
            //Always get fields in numerical order, such as 1 then 2 the 3 etc.
            print strFmt("%1 - %2", strRTrim(resultSet.getString(1)), strRTrim(resultSet.getString(2)));
        }

        //Close the connection.
        resultSet.close();
        statement.close();
    }
    else
    {
        error("Failed to log on to the database through ODBC.");
    }
}

I recently had the problem that when i synchronize the database in the form database Synchronize database errors and/or warnings have been issued, in which i was sure that these have already been resolved.

A simple solution to this behaviour is to delete the contents of the table SqlSyncInfo.

The table can be found in the AOT under System Documentation > Tables > SqlSyncInfo.

Incidentally, there is also the form SysSqlSync, which can be opened at any time and there you can view the result of the last synchronization.

Using the report CustTransList (Accounts receiveable > Reports > Transactions > Customer > Transaction) i would like to demonstrate, how it is possible to call a report in a other language, the the client is currently running in.

There are no classes available for this report, so i have to cretae my own one:

class CustTransListController extends SrsReportRunController
{
}

public static str getReportName(Args _args)
{
    str reportName = ssrsReportStr(CustTransList, Report);
    return reportName;
}

public static void main(Args _args)
{
    CustTransListController  controller = new CustTransListController();
    controller.parmReportName(CustTransListController::getReportName(_args));
    controller.parmArgs(_args);
    controller.parmReportContract().parmRdlContract().parmLanguageId('en-us');
    
    controller.startOperation();
}

Using this class now it is possible, to run the report in every language (which should be provided using the parmLanguageId()-method.

Following display-method (created in the datasource of the form custtable) shows the  financial dimension Costcenter.

public display DimensionValue showCostCenter(CustTable _custTable)
{
    DimensionAttributeValueSet dimensionAttributeValueSet;
    DimensionAttributeValueSetItem dimensionAttributeValueSetItem;
    DimensionAttributeValue dimensionAttributeValue;
    DimensionAttribute dimensionAttribute;

    #define.CostCenterDimensionName("CostCenter");
 
    if( !_custTable || !_custTable.DefaultDimension)
    {
        return '';
    } 

    dimensionAttributeValueSet = DimensionAttributeValueSet::find(_custTable.DefaultDimension); 

    select firstOnly RecId
    from dimensionAttributeValueSetItem
        where dimensionAttributeValueSetItem.DimensionAttributeValueSet == dimensionAttributeValueSet.RecId
    join DimensionAttributeValue
        where DimensionAttributeValue.RecId == dimensionAttributeValueSetItem.DimensionAttributeValue
    join RecId from dimensionAttribute
    where dimensionAttribute.RecId == DimensionAttributeValue.DimensionAttribute
       && dimensionAttribute.Name  == #CostCenterDimensionName
    

    if(dimensionAttributeValue && dimensionAttribute)
    {
        return dimensionAttributeValue.getValue();
    }

    return '';
}

Simpler version (see comments)

public display DimensionValue showCostCenter(CustTable _custTable)
{
    #define.CostCenterDimensionName("CostCenter");
 
    return ((select firstOnly DisplayValue from DefaultDimensionView
             where DefaultDimensionView.Name == #CostCenterDimensionName
                && DefaultDimensionView.DefaultDimension == _custTable.DefaultDimension).DisplayValue);
}
