Hi All,

New Custom Model Objects are not getting extension creation option in existing Custom Model.

I checked Models Layer, both are in VAR layer, in referenced packages, model is selected.

Pl. advice.

Thx in advance.

    Yes correct, it's not about the old and new model - I am explaining, as he is saying 2 model as New model and old model.

    Thanks,

    Girish S.

    As per my understanding, its not about old and new models but the Top level models can access the bottom one, create Extension is not possible for lower model (lower model can't create extensions for objects from higher one).

    Hi Mohit,

    Attached screen shot.

    From above reply of Girish, We can't create extension of New Model objects in Old Model, when Old model is selected as a reference package for New Model.

    You may re check at your end.

    Thx & Regards..

    Yes , you understood correctly Girish.

    Backward compatibility won't work, sounds logical as well.

    Many Thx !!!

    Please share screenshot of your model parameters (the one which have the elements to be extended and another where you want to extend). We have two VAR models and Create Extension is working.

    If I understood correctly - You have two models "Old model " and New model" - In the "New model" you are referring to old model as a reference.

    Now you want to access the class from "New model" into "Old model" which is not possible. You are trying to refer the model in backward which is not possible - You can access object of "Old model" in "New model" but not vice versa.

    Thanks,

    Girish S.
