Within PD head to the "Catalogue" tab and select the "Cat. Price Variance" sub-tab. 

This table will show you all of the products where your most recent price was different to your catalogue price, it includes when these prices were paid and the overall variance for each product.

Any questions at all please do not hesitate to reach out to the support team at support@adviseinc.co.uk

If you would like more training on how to use this tab you can head over to Litmos and watch the 'Catalogue Tab' training video under "Procurement Dashboard - Intermediate Course"
