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.
Create one custom post type and assign it to two different Oxygen templates.
There is no option to create a post of a post type from another post type like that. If you are familiar with coding, you can use the WordPress function wp_insert_post() to create a post of a post type.
