Retail merchandising condition executed by retailers and measured using the retailer’s POS system. This measure is calculated (from prices obtained from the POS system) not collected from retailer features or from what is displayed on a shelf price tag. A TPR is a temporary price cut of at least 5% from the regular price. In both IRI and Nielsen data, after 7 weeks, the TPR price becomes the new regular price.

How is TPR collected. Thank you Ramesh
TPR is a calculated measure, based purely on the scanned pricing. IRI/Nielsen have an estimate of regular price (they call it Base Price). When the actual scanned price is at least 5% lower than the base price, IRI/Nielsen assume a temporary price reduction (TPR). If the “temporary” price reduction persists for more than 7 or 8 weeks (the exact number varies by vendor) then it will no longer be considered “temporary” and will be the new base price.
