Users are also able to view the Purchase Order Balance. The PO Balance report shows the remaining amount for each PO, with the balance being calculated as follows:
PO amount minus the amount of all open and approved Bills matched to it.
However, this is only the case if you select the ‘Many Bills – One PO’ pattern when you’re doing the matching. If you select ‘One Bill – Many POs’, the Purchase Order Balance cannot be calculated, and will therefore not be shown in the report.
