Number Sequence in Dynamics AX 2012 – Part 2

Create a Number Sequence from Scratch

Now we will implement a Number Sequence in an existing Form.


Create a Number Sequence HCMEmploymentLeave form.


We will take a few steps to achieve this.

In this example, we will create a Number Sequence from scratch for Employment leave. The Form and the table which we are going to use are “HCMEmploymentLeave” and “HCMEmploymentLeave”. Please note that you might see few fields

Step 1: Create an EDT of type string

Here we have create EDT with name HCMEmploymentLeaveId

16-Create-an-EDT -of-type-string

Step 2: Drop the EDT in the field of table you plan to make sequence number for

17-Drop-the-EDT -in-the-field-of -table

Step 3: Add the code in the NumberSeqModule###

18-Add-the-code -in-the -NumberSeqModule

Step 4: Create a method in HRMParameterTable to return the Number Sequence Reference

19-Create-a -method-in -HRMParameter -Table -to-return -the-Number -Sequence -Reference


Step 5: Declare NumberSeqFormHandler in the Form “HCMEmploymentLeave”

20-Declare- NumberSeqFormHandler-in-the -Form

Step 6: Add the NumberSeqFormHandler method to the form

21-Add-the -NumberSeqFormHandler-method -to-the-form

Step 7: Add create(), delete(), write(), ActiveLink() and validateWrite() methods to the methods of Data Source of the Form

HCMEmploymentLeave: Create()

public void create(boolean _append = false)


HCMEmploymentLeave: delete()

public void delete()

HCMEmploymentLeave: write()

public void write()

HCMEmploymentLeave: close()

public void close ()
if (numberSeqFormHandler)


Step 8: Create a Job with following code and Run

static void NumberSeqLoadAll (Args _args)



 Step 8: Create a Job as below and Run

22-Create-a -Job

Step 9: Check and verify that the Number Sequence have been created for the reference

The process is same as described in the section Create a new Number Sequence.


23-Check-and -verify-that-the -Number Sequence

Implement the Number Sequence and see it in action


25-Implement-the -Number -Sequence


24-Implement-the -Number -Sequence
