Purchase Information Record or PIR stores the information for a material beyond material master. It is built upon the information available for a material and the specific vendor who supplies it. Hence, it corresponds to a vendor and can be mapped against a purchasing group as well. When a purchase order is created, PIR is used to populate data at item level like purchasing group and net price based on the material and the vendor which supplies the material.
The procurement of material defines the info category of a PIR. There are four categories –
Based on the selected info category, SAP Standard pulls out the relevant information. For example, consider Standard. It captures information like – planned delivery time, standard quantity and UOM specifics, Net and effective price, Vendor data, Origin data etc. This information flows into the PO and by copy control, into downstream documents.
