How can I create entities having the same basic Enity, so that I can show different entities in the same view based on the basic entities.

Hi,
You should create a screen according to this example. Here we have two entities with the same parent. For each entity, we create a collectionDatasource and a table with this datasource. For creating or updating entities you should generate standards screens.
