How to re-link SO and PO

ERPNext
1

Hi There!

I am using v.15. I have created SO and PO basing on it. There was connection between them. However, I had to cancel and amend SO for unrelated to Item fields. I saved and submitted SO, but now connection is broken. So, I have 2 questions:

  1. How to re-establish connection between SO and PO?
  2. How to avoid it in future if I need to make some minor changes in SO or PO unrelated to Items?

thanks!

Hi Guys, no one can help here?

What is the logic of ERPNext for connecting PO and SO? If i had to amend SO - do i need to cancel the whole thing and start again? What if customer asks to change delivery address to another warehouse? It’s a system field, that I can’t “Allow on Submit”

thanks.
