# Fishbowl: "PO may already exist for this sales order"

> The system warns that a purchase order may already be linked to this sales order.

## What it means
When creating a purchase order from a sales order, Fishbowl tracks whether a PO has already been linked to that SO. This warning appears if the system detects an existing or potential PO relationship, asking you to confirm before proceeding. It's a safeguard to prevent unintentional duplicate POs.

## What to check
- Look up the sales order to see whether a PO is already linked to it
- Confirm whether you intended to create a new PO (for example, splitting the order across multiple vendors) or if this is an accidental duplicate attempt
- If you're certain no PO exists for this SO, you can safely proceed; otherwise cancel and review the existing PO
