Customizing Dynamics AX 2009 : Number Sequence Customization

The properties on the extended data type are set to create a type with a maximum length of 20 characters, as shown in Table 1.

To implement a number sequence reference for service orders and assign it a specific service order number sequence, you must make changes to a NumberSeqReference class. To implement the reference in the Accounts Receivable module, among other references used by the sales order functionality, you add the following lines of X++ code to the loadModule method on the NumberSeqReference_SalesOrder class.

numRef.DataTypeId             = typeId2ExtendedTypeId(
                                typeid(BikeServiceOrderId));
numRef.ReferenceHelp          = "Unique key for the service order table, "+
                                "used when identification of a service "+
                                "order is allocated automatically.";
numRef.WizardContinuous       = false;
numRef.WizardManual           = NoYes::No;
numRef.WizardAllowChangeDown  = NoYes::No;
numRef.WizardAllowChangeUp    = NoYes::No;
numRef.SortField              = 100;
this.create(numRef);

These are the only modifications necessary to set up a new number sequence reference. The reference is available in the Accounts Receivable parameter form, and a number sequence can be created automatically by using the Number Sequence Wizard. You start the Number Sequence Wizard by clicking the Wizard button in the Number Sequences form located in the navigation pane under Basic\Setup\Number Sequences\Number Sequences.

The numRef table buffer in the preceding example is of a NumberSequenceReference table type. This table contains several fields that can be set depending on the reference you want to create. These fields are described in Table 2.

Finally, the following method is implemented on the SalesParameters table. The method returns the new number sequence reference and should be used in the X++ code that requires numbers from the number sequence.

static client server NumberSequenceReference numRefBikeServiceOrderId()
{
    return NumberSeqReference::findReference(
                           typeId2ExtendedTypeId(typeid(BikeServiceOrderId)));
}
