This document provides an overview of PI sheets in SAP, which can be used to inform production operators of steps to perform. There are two types: ABAP-based and browser-based. Browser-based PI sheets are configured by defining master data like materials and BOMs, transporting standard SAP settings, creating control recipes and destinations, defining process message characteristics, assigning process instructions to recipes, releasing control recipes to generate PI sheets, and using the sheets to record operator inputs and update order data. PI sheets allow recording of various production activities and values in a flexible manner.
