How to access individual field on the form using form data source?
myTable_ds.object( fieldNum( myTable, myField ) ).visible( false );

How to create an auto lookup without writing code where Field 2 lookup is based on Field 1 Value?
In order to achieve this create a relationship in the related table but make sure Field 1 is the first relation in the relationship and Field 2 is the second relation. This can be done by actually creating Field 2 relation before Field 1.

How to create a simple dialog box?
Dialog      dialog;
DialogField field;
   
dialog = new Dialog("My Dialog");
dialog.addText("Select your favorite customer:");
field = dialog.addField(ExtendedTypeStr(CustAccount));
dialog.run();
if (dialog.closedOk())
{
info(field.value());
}

How to convert string to enum?
SMATransactionType  transactionType;
transactionType = str2enum(transactionType, "Hour");
info(enum2str(transactionType));

Date Time Affectivity
utcDateTime fromDateTime, toDateTime;
fromDateTime = DateTimeUtil::newDateTime(3\3\2012, 0);
toDateTime   = DateTimeUtil::maxValue();

#Selecting a time effective record based on from date
select validTimeState(fromDateTime) table;

#Selecting a time effective record based on from date and to date

How to create manual auto numbering system?
A technique I used in HR was as below,

// >>> abdul @ 3rd June 2014 / Get New Auto Number Based On Company
public static str getNewPersonnelNumber()
{
    int maxLenght = 4;
    str tempEmployeeID;
    str newNumber;

    HCMWorker localWorker;
    str ret;
    str 2 companyIdFilter;

    //Pickup the first digit as company name
    companyIdx = String::trimToLength(curext(), 1);
    companyIdx = strUpr(companyIdx);
    companyIdFilter = companyIdx + '*';
    select firstOnly localWorker
        order by localWorker.PersonnelNumber desc
        where localWorker.PersonnelNumber like companyIdFilter;
    tempEmployeeID = localWorker.PersonnelNumber;
    newNumber = String::replaceAll(tempEmployeeID, companyIdx, "");

Grid.setTmpData(temporaryTabeReference);


Lookups
How to create simple lookup?
Simple lookups can easily be created by adding a relation between the tables.

How to create a dynamic lookup?
In order to create a dynamic lookup there are two steps,
Step1: Create a lookup method in table or class
public static void lookupVendorByCurrency(
    FormControl _callingControl,
    CurrencyCode _currency)
{
    Query query;
    QueryBuildDataSource qbds;
    QueryBuildRange qbr;
    SysTableLookup lookup;
   
    query = new Query();
    qbds = query.addDataSource(tableNum(VendTable));
    qbr = qbds.addRange(fieldNum(VendTable, Currency));
    qbr.value(queryvalue(_currency));
    lookup = SysTableLookup::newParameters(tableNum(VendTable), _callingControl, true);
    lookup.parmQuery(query);
    lookup.addLookupField(fieldNum(VendTable, AccountNum), true);
    lookup.addLookupField(fieldNum(VendTable,Party));
    lookup.addLookupField(fieldNum(VendTable,Currency));
    lookup.performFormLookup();
}

Step2: Call the lookup method from the overridden lookup method on the data source field
public void lookup(FormControl _formControl, str _filterStr)
{
    VendTable::lookupVendorByCurrency(_formControl, CustTable.Currency);
}


Display Method Caching
Display methods must be written at table levels, in AX 2012 you can also use cache display method property of form controls.
CustTable_ds.cacheAddMethod(tableMethodStr(CustTable, name), false);

static void Carid(Args _args)
{
    NumberSeqModuleProject  NumberSeqModuleProject = new NumberSeqModuleProject();
    ;
    NumberSeqModuleProject.load();
}
5. Then run the wizard
Organization Administration >> CommonForms >> Numbersequences>>Numbersequences>> Generate >> run the wizard.
6.Now we have to check the number sequence  is correctly working  for that write a job:
static void number(Args _args)
{
    NumberSeq  numberSeq;
    CarId num;
    ;
    numberSeq = NumberSeq::newGetNum(ProjParameters::numRefcarId());
    num = numberSeq.num();
    info(num);
}
Run the above job.We will find the generated Number     sequence.                                                    .
7. Now we want that Number Sequence in form level(Car Table):
Declare the number sequence On Form Declaration:
public class FormRun extends ObjectRun
{
    NumberSeqFormHandler numberSeqFormHandler;

}
8. Write the NumberSeqFormHandler() in form methods node.
NumberSeqFormHandler numberSeqFormHandler()
{
    if (!numberSeqFormHandler)
    {
        numberSeqFormHandler = NumberSeqFormHandler::newForm(ProjParameters::numRefcarId       ().NumberSequenceId,
                                                             element,
                                                             CarTable_DS,
                                                             fieldNum(CarTable, Car Id)
                                                            );
    }
    return numberSeqFormHandler;
}
9.Write the close() on the form methods node.
void close()
{
    if (numberSeqFormHandler)
    {
        numberSeqFormHandler.formMethodClose();
    }
    super();
}
10. Then final add the below methods on data source methods node
Create()
void create(boolean append = false,
            boolean extern = false)  // If created externally
{
    element.numberSeqFormHandler().formMethodDataSourceCreatePre();

    super(append);

    if (!extern)
    {
        element.numberSeqFormHandler().formMethodDataSourceCreate(true);
    }
}
Delete()
public void delete()
{
    element.numberSeqFormHandler().formMethodDataSourceDelete();
    super();
}
Write()
public void write()
{
    super();
    element.numberSeqFormHandler().formMethodDataSourceWrite();
}
Validate Write()
public boolean validateWrite()
{
    boolean         ret;
    ret = super();
    ret = element.numberSeqFormHandler().formMethodDataSourceValidateWrite(ret) && ret;
    if (ret)
    {
        CarTable.validateWrite();
    }
    return ret;
}
Link Active()
public void linkActive()
{
    ;
    element.numberSeqFormHandler().formMethodDataSourceLinkActive();
    super();
}
Now our numberseqence is generated .
*** Set the field or Tabpage Allowedit property to No.
***Check the continues on wizard.
