Pass data from one past type to another

Here is my scenario;
1. I have two post types "A" and "B"
2. When I enter data in post type "A", I would like the data passed to post type "B" and create a new entry.
3. Both post type "A" and "B" has their own custom templates in OxygenBuilder(now support Metabox) with additional information specific to each post type.

Alternatively

Create one custom post type and assign it to two different Oxygen templates.

Any help will do.
Thanks
