Implementing table extension framework in Dynamics AX

March 23rd, 2017 Intech Systems Dynamics AX, Microsoft Dynamics

To implement the table extension framework in Dynamics AX  2012 R3, following are the steps:
Assume that you have table SalesLine and you want to make extension table ISPLSalesLineExtension.

Step – 1: Add Relation

At SalesLineExtension table, add new relation named SalesLine, table SalesLine.

Add a new field ForeignKey -> PrimaryKey based at newly created ISPLSalesLineExtension table. Reference field to the primary table will be added automatically.

Note: if the parent table’s primary key is not RecId-based, but the table has CreateRecIdIndex property set to Yes, then the relation on step #1 should be created based on “Single field AlternateKey based”; otherwise the new field will potentially have wrong type, and it will not be possible to use it in the SysExtensionSerializerExtensionMap map.

Step – 2:  Create a unique index for the reference field that points back to SalesLine .

Step – 3 Integrate with the table extensions framework

Add parent table (SalesLine – If it is standard table it might already be exist) to SysExtensionSerializerMap and child table (ISPLSalesLineExtension) to SysExtensionSerializerExtensionMap

Step – 4: Create methods at ISPLSalesLineExtension table

Step – 5: Create new field PackedExtensions in SalesLine.

This field is available in standard table (Check if already exists)

Step – 6: Add a delete action from the SalesLine to the ISPLSalesLineExtension table.

Step – 7:  Create/Update methods at SalesLine table

Step – 8: Modify below methods on parent table. (SalesLine)

Check if code already exists if it is a standard table.
public void insert()
{
super();
this.SysExtensionSerializerMap::postInsert();
}
public void update()
{
super();
this.SysExtensionSerializerMap::postUpdate();
}

Step – 9: Please be aware that write method of parent data source (SalesLine) should be modified:

 public void write()
{
super();
ISPLSalesLineExtension.SysExtensionSerializerExtensionMap::insertAfterBaseTable(SalesLine);
}
Write Method of child table triggers first and as a result child record will not be saved as it’s insert and update methods does not allow it without correct foreign key.

Step – 10: Modify Form Code as per below
