The option to click on SalesOrder in the Purchase Order (PO) is unavailable. You can use the Purchase Order (PO) number as your basis when you open the Sales Order. In the PO you can also see the Sales Order number under the MEMO field. This way you can identify which transaction is attached to the other.
I'll personally send this as feedback to our engineers about having a way for you to click a link or report in the Sales Order and it'll route you to the linked PO.
Thank you for your feedback. Unfortunately in our situation that won't work as many of our customers (who see the Sales Order) have their own PO # that needs to be referenced for their order. We mill flooring (mostly) per order so our method works something like this:
1. customer places order, a Sales Order is created
2. from the Sales Order we create a Purchase Order and send to our shop to have it milled
3. the shop mills the order and then calls it ready by it's PO#
This works great for finding the SO it is attached to because (as your attachment shows) this appears in the PO Memo window so we know exactly which job it is they are calling ready. Where we get in trouble is when a customer calls in to check on the status of their order they give us their SO #. We then have to go search for the corresponding PO# because it is not tied to the SO in the system when going this direction. I was hoping there was some way to see from the SO which PO was created from it but after many searches and reports I do not believe there is a way.
