Hi,

I would like to know how to override a table method for example Insert() method using extension.

Also i am trying to add aosValidateInsert() and aosValidateUpdate() to an extension class for the same table but i am getting an error that it is marked for internal use only:

So, how can i add these methods to the table!!

No, you can't create derived classes of tables or forms.

Class hierarchies are not supported on tables and forms, only on classes.

Thanks,

This method into table (WorkflowWorkItemTable), I tried to right click and view code then it opened (public class WorkflowWorkItemTable extends common) that contains all default methods.

Can i create a derived class, override this method and do not call supper. Then using CoC extend constructor to instantiate derived class instead of original?

Insertion will be done in all cases. Like you have been told many times already, you can't skip the execution of the standard logic by extending it.

However in ValidateWrite you can add your own checks after calling next(), and return false if your custom validations fail. If the validation fails, the data will not be inserted. But only if the "inserter" calls validateWrite (it's always called when data is inserted/updated from forms, but in x++ it's possible to not call it).

Hi Nikolaos,

You said that I can't prevent the standard code. Do you mean that the insertion will be done in all cases??

There is no way to set a condition?? As I think if I moved my code to validateWrite I will have the same problem as I will not able to set a condition too.

You need to refactor your code and reimplement it with Chain of Command.

In my opinion all validations (that might prevent the insertion) belong to validateWrite, not insert method.

But you can also use Chain of Command with the insert method, and update/delete the record after it's been inserted (and populated with the standard values).

You can't prevent the standard code from being executed, but you can do your magic before or after it.

Hi,

Thanks for your replies.

Actually, I am upgrading from AX 2012 to D365 FO. I have a Table\Insert( ) method with a customizations that need to be migrated.

The original method is as follow:

public void insert()

{

this.Subject = SysEmailMessage::resolveUrls(this.Subject, false);

this.Description = SysEmailMessage::resolveUrls(this.Description, false);

super();

}

The customized code into AX 2012 (highlighted in red) that need to be migrated is as follow:

public void insert()
{
    boolean Insert=true;
    PurchReqLine PurchReqLine;

    this.Subject = SysEmailMessage::resolveUrls(this.Subject, false);

    select firstOnly Category from workflowTable
    where workflowTable.ConfigurationId == this.ConfigurationId;


   if (workflowTable.Category != WorkflowInstanceCategory::LineItemWorkflow)
    {
        this.Description = SysEmailMessage::resolveUrls(this.Description, false);
    }

    if(this.RefTableId == tableName2id('PurchReqLine'))
    {
        select * from PurchReqLine where PurchReqLine.RecId==this.RefRecId;
        if(PurchReqLine && PurchReqLine.RequisitionStatus==PurchReqRequisitionStatus::Rejected)
        {
            this.Status=WorkflowWorkItemStatus::Completed;
            this.Type=WorkflowWorkItemType::WorkItem;
            Insert=false;
        }
    }

    if(Insert)
      super();
}

Hi Peter

I would take note of everything everyone else has said here.

As for chain of command, you don't use super, you use next as described here:

https://docs.microsoft.com/en-us/dynamics365/unified-operations/dev-itpro/extensibility/method-wrapping-coc

You're basically looking at something like this:

[ExtensionOf(tablestr(YourTable))]
final class YourTable_Extension
{
    public void yourMethod()
    {
        next yourMethod();
        //...
    }
}

Hope this helps

Is there a specific reason you can't use validateWrite(), insert() or update() ?

You can't override the standard table / form methods in D365FO.

You can hook into standard events such as onInserting. Or use Chain of Command on the methods (not sure if all framework table methods are supported for CoC yet or not).

Hi Peter,

If you have a business requirement to override the aosValidateInsert and/or aosValidateUpdate methods, you can create extensibility requests for it. First check if the latest release (10.0.1 or 10.0.2) has the same issue with having these methods marked as internal only.

Override Insert() method into a table Dynamics 365 F&O

public void insert()

{

this.Subject = SysEmailMessage::resolveUrls(this.Subject, false);

this.Description = SysEmailMessage::resolveUrls(this.Description, false);

super();

}

public void insert()
{
boolean Insert=true;
PurchReqLine PurchReqLine;

this.Subject = SysEmailMessage::resolveUrls(this.Subject, false);

    select firstOnly Category from workflowTable
    where workflowTable.ConfigurationId == this.ConfigurationId;

if (workflowTable.Category != WorkflowInstanceCategory::LineItemWorkflow)
    {
        this.Description = SysEmailMessage::resolveUrls(this.Description, false);
    }

if(Insert)
super();
}
