Posted on by @rp@n

Dear All,

Can you please let me know if we are going to work with Standard Objects on Table, View, Queries and Data Entities. So, we need to work with Extensions.

I saw for each Objects we have extension. Like Table. extension, View.extension etc...

For example :

If i need to work with Standard View. So,create my own view.extension to work OR we can work directly with objects under View.extensions?

Please give me more shed on this.

Thanks!

Please define what you mean by "to work". A concrete example would likely help.

You seem to be completely ignoring packages, which is a big mistake. The answer depends on whether the "extension which is already present" is in your package or not.

You can modify elements (including extensions) that are in your package. You can't change code in packages developed by other parties, such as Microsoft or ISVs. You can only extend them, which is the point of extensions.

Thanks Sukrut,

Means It's might be Table, View, Queries Or Data entities. If we need to add any extra code depends upon my business logic so, I need to create my Own Package and own extension respectively.

And the Extensions which is created by Microsoft, we can only extend this if required but it's not allow me to do any customization.

Is't correct ?

Please give me more shed on this.

Thanks!

Basically if you want to change anything that is not in your package, you have to create an extension. You can't modify objects that are in other packages, no matter if they are normal objects or extensions.

In earlier versions of D365FO and AX, Microsoft allowed others to customize the standard package. Now it's no longer possible.

Thanks Nikolaos,

For example : BaseEnum : Bank Account Type

It's showing it's belong to Package ( Bank Type )

If i need to add any element on base enum BankAccountType So, i need to create my Own Package and Own extensions. Then only i can add elements in enum Bank Account Type.

Is't correct ?

Please give me more shed on this.

Thanks!

Thanks Sukrut,

Means suppose first time i am creating Package ( MyOwnPackage ) and Create Extensions.

If required, Next time on wards i need to choose "Select Existing Package " and from drop down need to select my package ( MyOwnPackage). So, that i can add multiple objects in single Package.

Is't correct?

Please give me more shed on this.

Thanks!

"Select Existing Package" is related to creating models.

I assume it's not what you're talking about. If you want to add objects to an existing model, either open an existing project for the model or create a new project and make sure its for the model where you want to add things. (You can change it in model properties.

You'll use "Select Existing Package" only if you want to create more models inside the same package, which you won't do often.
