All companies with an Address Type = Ship To need to be 'linked' to a company with an address type of Bill To or Both. This can be accomplished in 2 ways:
1--Automatically. When you are on a transaction screen, like the QPC or Sales Order, if you have already selected a Bill To address and then type a NEW Ship To address (meaning you enter one that is not already in the drop down list), OneSource will automatically LINK that Ship To address to the Bill To address you have already selected.
2--Manually. If at any time you want to change or re-link a Ship To address to a different Bill To address, you can do this looking up the Ship To company (F3) and then changing the Bill To company to the company of your choice. (Note: The company you choose has to have an Address Type = Bill To, or Both).
