Reports can be created for each part of the workflow in the PO module (excluding Create)
To run a PO report
Open the details view of the PO module.
Select the PO's you would like to create a report of (if applicable) by checking the box next to Status.
If you are creating a report for the selected PO's, then choose 'Selected'. If you are creating a report for all PO's showing in the details view, choose 'Filtered'.
Making custom reports becomes easy using the filters and reporting on what you see in your screen.
Choose 'CSV' or 'PDF'. CSV will give you all the data in a format easy to manipulate and PDF will give you a preformated report.
