Is there a way to change the super type of a custom type?

Hi,

Is there a way to change the super type of a custom type? Currently the super type of my custom type is dm_document. I need to change the super type to be another custom type.

CURRENT:

dm_document -> my_custom_type

NEED TO MAKE:

dm_document -> another_custom_type -> my_custom_type

Note: another_custom_type already exists.

If needed I can delete all objects of my current 'my_custom_type'.

Note: I can recreate my_custom_type with another_custom_type as super type, but I think it is not the best approach.

We are using DCTM 6.7 with Composer.

Please share your knowledge and experiences for figuring this out.

Thanks.

That selection is showing all types registered in you project and in the core project, I think. You need to import the type from the repository (File > Import... | Artifacts) and then it will appear in that list.

There is no support for changing the type hierachy has you want. All support is for changing the type of a particular object with the "CHANGE ... OBJECT" if I'm not mistaken.

Has you mentioned, you will have to recreate 'my_custom_type' under 'another_custom_type'.

I don't know your requirements but the type hierarchy is supposed to change only during development. You can always create types, change, and drop types, in your application, but then aspects would probably be a better solution for you.

Thanks Claudio.

I am using development mode. It is not in production yet. I am not sure how I can get it using Aspects because it is entirely new to me. I think the best approach is to recreate 'my_custom_type' under 'another_custom_type' for now.

Thanks.

Hello Athati, The good question is have you got already lot of "my_custom_type" object ? If not, just drop the type and recreate it.

Hi ,

I would suggest that you create a new object type with supertype as your "another_custom_type"

---->>> dm_document->another_custom_type->custom_object_new

Then change the existing document's type to your new custom type by DQL.

CHANGE my_custom_type (ALL) OBJECTS TO custom_object_new

WHERE <your_filter_condition>

Sagar,

The Change type only works to change an object to it parent object or to it child object. It cannot works in this case.

Hi Athathi...

First you need to delete all the object related to my_custom_type object.

As you already have my_custom_type in your composer you can change the Supertype.

Delete the my_custom_type object from your repository and run data dictonary and clear cache..

Install the updated my_custom_type using composer.

Also it is good practise to mark comments as Helpfull/correct answer.

Thanks yamangoyal.

I tried to do the same you mentioned, but the slection of new super type is not showing up my custom types from which I want to select my new super type. Please see the attachment and advie me.

Thanks.
