How can I add new data from one doctype to another directly

Hi I want to add information data directly from doctype to another.

What do you mean “directly from doctype to another”? Without passing by the code?
If not, you can just overwrite the save button in the first doctype?

Do you have any additional information/Can you clarify what you want?

thank for replying
I just want to generate data in Doctype that sends it to others without having to add them to the others manually
