Number Sequence for existing module in ax 2012

 NumberSequence for  the Existing module
To create a numbersequence for  the Existing module.
Suppose in my HRM Module for the Employee Table I have to create the NumberSequence  (EmplTable).
I need to follow these steps to create the NumberSequence  .
 Go to the Classes -> NumberseqReference_HRM (Class) -> LoadMethod

In the load method you have to override the code , need to added the code to which field we are planning to add the code that it can be copied from the exisitng code and modfiy the EDT which we want to add   ( Here My EDT is EmplId)

Let us Assume (Existing Code )
numRef.DataTypeId = typeId2ExtendedTypeId(typeid(HRMApplicationId));


For The Empl Id We have to add the code means

numRef.DataTypeId = typeId2ExtendedTypeId(typeid(EmplId));


After completing the above procedure, we have to go to AOT -> Tables ->HRM Parameters -> Need to Override the code  in the method
Ex: The Overrided code is

static client server NumberSequenceReference numRefEmplId()
{
    return NumberSeqReference::findReference(typeId2ExtendedTypeId(typeid(EmplId)));
}

Same code u copy as per u r requirement in there see the below screen shot

After the above step go to the Empl Form -> Form Level Methods u have to write the number sequence formhandler method have to create the code.
See the below figure.


Class declaration Code
IN the class declaration we have to write the code

NumberSeqFormHandler numberSeqFormHandler;

Numberseqformhandler Code
In the Numberseqformhandler write the below code

NumberSeqFormHandler numberSeqFormHandler()
{
    if (!numberSeqFormHandler)
    {
        numberSeqFormHandler = NumberSeqFormHandler::newForm(HRMParameters::numRefEmplId().NumberSequence,element, EmplTable_ds, fieldnum(EmplTable, EmplId));
    }
    return numberSeqFormHandler;
}

Then we have to Override  the DataSource Methods ( Create, Write ,Delete).

Write Method Code is
element.numberSeqFormHandler().formMethodDataSourceWrite(); ---- After Super

Create Method is
element.numberSeqFormHandler().formMethodDataSourceCreatePre(); - Before Super
super();
  element.numberSeqFormHandler().formMethodDataSourceCreate(); --- > After Super
Delete Method Code Is
element.numberSeqFormHandler().formMethodDataSourceDelete();---- After Super

After completing all the above steps.
Go -> HRM Module -> Setup -> Parameters -> Numbersequence


We have to add the reference for the EMP ID. To add the reference see the below screens .
