Inquiry on Importing Models and JCos

Question

Hi!
I currently have a project, which requires me to re-import a set of ABAP modules in my Web Dynpro app. In addition to this, I also need to change the JCo Model Data and Meta Data destinations for this.
My questions are:
1.) Is there a way to change the Model Data nad Meta Data JCos without having to delete the model and import again? I tried reimporting it, but it doesn't let me change the JCo definitions (or at least I don't know if how and if it is possible).
2.) If I do delete the Model and import it again, what will happen to the existing implementation codes that uses the model in the WD? What gets removed and what gets retained?
That's all! Thanks!

Hi Angelo,
To change the metadata without deleting the model,
Expand Dictionary under the project created, you will find one dictionary type of the same name of you model. Select it in the properties you can see the Metadata data of the model, change it, save, build and deploy
To change the model data without deleting the model,
Expand Project --> models --> model name --> model classes. Click on each model class in the properties you can see the model data, change it, save, build and deploy.
Hope this solves your problem.
2.) If I do delete the Model and import it again, what will happen to the existing implementation codes that uses the model in the WD? What gets removed and what gets retained?
Even if you reimport your model with the same name as it was before deleting you may need to recheck all the context mapping and binding of UI elements with the model data in your project to ensure its correctness.
