Generate number Sequence in AX 2012

Generate number Sequence

Suppose we want create number sequence for Test field on form in General  ledger module

Consideration: EDT-Test, Table-TestTable and Form- TestTable

Step1. Create new EDT with name Test

Step 2. Modify load module() method on  NumberSeqModuleLedger class

{

     datatype.parmDatatypeId(extendedTypeNum(Test));

     datatype.parmReferenceHelp(literalStr("Test"));

     datatype.parmWizardIsManual(NoYes::No);

     datatype.parmWizardIsChangeDownAllowed(NoYes::No);

     datatype.parmWizardIsChangeUpAllowed(NoYes::No);

     datatype.parmWizardHighest(999);

     datatype.parmSortField(30);

     datatype.addParameterType(NumberSeqParameterType::DataArea, true, false);

     this.create(datatype);

}

Step 3.Create a method on LedgerParameters Table

     client server static NumberSequenceReference numRefTest()

{

     return NumberSeqReference::findReference(extendedTypeNum(Test));

}

Step 4.Write and run following job

static void NumberSeqLoadAll(Args _args)

{

    NumberSeqApplicationModule::loadAll();

}

Step 5.Then run the wizard

Organization Administration -> CommonForms -> Numbersequences->Numbersequences-> Generate -> run the wizard.

Step 6.Now we have to check the number sequence  is correctly working  for that write a job:

static void NumSeq(Args _args)

{

    NumberSeq  numberSeq;

    Test num;

    ;

    numberSeq = NumberSeq::newGetNum(ProjParameters:: numRefTest ());

    num = numberSeq.num();

    info(num);

}

Step 7.Now we want that Number Sequence in form level(Test Table):

 Write below code in class declaration  

public class FormRun extends ObjectRun

{

    NumberSeqFormHandler numberSeqFormHandler;

}

 Step 8.Write the NumberSeqFormHandler() in form methods node.

NumberSeqFormHandler numberSeqFormHandler()

{

    if (!numberSeqFormHandler)

    {

       numberSeqFormHandler = NumberSeqFormHandler::newForm(LedgerParameters:: numRefTest ().NumberSequenceId,

                                                             element,

                                                             TestTable_DS,

                                                             fieldNum(TestTable, Test)

                                                            );

    }

    return numberSeqFormHandler;

}

Step 9.Write the  Create(),Delete(),Write() , Validate Write(),Link Active() on the Data source methods node.

 Create() Method

void create(boolean append = false,

            boolean extern = false) 

{

    element.numberSeqFormHandler().formMethodDataSourceCreatePre();

    super(append);

    if (!extern)

    {

        element.numberSeqFormHandler().formMethodDataSourceCreate(true);

    }

}

Delete() Method

public void delete()

{

    element.numberSeqFormHandler().formMethodDataSourceDelete();

    super();

}

Write()Method

public void write()

{

    super();

    element.numberSeqFormHandler().formMethodDataSourceWrite();

}

Validate Write() Method

public boolean validateWrite()

{

    boolean         ret;

    ret = super();

    ret = element.numberSeqFormHandler().formMethodDataSourceValidateWrite(ret) && ret;

    if (ret)

    {

        TestTable.validateWrite();

    }

    return ret;

}

Link Active() Method

public void linkActive()

{

    ;

    element.numberSeqFormHandler().formMethodDataSourceLinkActive();

    super();

}

Step 10.Finally add Close() method on form

void close()

{

    if (numberSeqFormHandler)

    {

        numberSeqFormHandler.formMethodClose();

    }

    super();

}
