To add a PO number prefix, follow the instructions below.
1. On the toolbar, click Settings.
2. On the Settings page, on the left sidebar, click Company Info.
3. On the Purchase Order Settings section at the bottom, enter your preferred PO Number Prefix. For example, if you put OM as the prefix, OM will be added to the PO number every time a PO is generated. Thus, your first PO number will read as OM1000, instead of just 1000, which would be the case if the PO number prefix remains blank.
4. Click Update.
Note: This is the only place in Extensiv Order Manager to customize PO numbers. That means that you cannot use different PO prefixes conditionally. All POs created regardless of Vendor/Warehouse will have this prefix.
