Steps to create a Number sequence

steps: to create a Number sequence

1.  Create an edt : CarId .

     AOT >> Extended Data Types(String) >> New  >> Properties >> Name  >> Car Id.

2. Write a code on lode module() on NumberSeqModuleProject

{

     datatype.parmDatatypeId(extendedTypeNum(Car Id));

     datatype.parmReferenceHelp(literalStr("@SYS334483"));

     datatype.parmWizardIsManual(NoYes::No);

     datatype.parmWizardIsChangeDownAllowed(NoYes::No);

     datatype.parmWizardIsChangeUpAllowed(NoYes::No);

     datatype.parmWizardHighest(999999);

     datatype.parmSortField(20);

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

     this.create(datatype);

}

3.Write a method on Projparameters Table

     client server static NumberSequenceReference numRefcarId()

{

     return NumberSeqReference::findReference(extendedTypeNum(car Id));

}

4.Write a job and run that

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 .
