In SAP, pegging is a procedure in Production Planning and Detailed Scheduling that establishes the relationship between receipt elements and requirement elements of a product. The purpose of pegging is to assign suitable existing product receipts and product stocks that can cover the requirement to a product requirement.
Pegging is an evaluation that displays the source requirements or the source procurement proposal of a chosen MRP (Material Requirements Planning) element in SAP. This evaluation is used to check the source of supply for a requirement element.
