SAP PI/PO message mapping converts data from one message format to another as it moves between systems, using tools such as graphical message mapping, Java mapping, or XSLT mapping. SAP PI/PO (Process Integration/Process Orchestration) is SAP's on-premises middleware; PI/PO 7.5 is its final release, with mainstream maintenance ending December 31, 2027, and SAP Integration Suite as the strategic successor.
Integration is critical for businesses because it lets them manage complex operations and processes across multiple systems, applications and departments. By integrating different parts of a business, organizations increase efficiency, reduce costs and improve customer experience. This guide explains what SAP PI/PO is, the mapping types it supports, and what its 2027 maintenance deadline means for your integration roadmap.
SAP PI/PO (Process Integration/Process Orchestration) is an integration solution SAP offers to create a unified system environment. As SAP's on-premises middleware, PI/PO helps organizations integrate applications both within and beyond the enterprise. It automates business processes across heterogeneous systems and provides tools to monitor, analyze and optimize those processes.
PI/PO 7.5 is the long-term stable, and final, on-premises release. SAP has set December 31, 2027 as the end of mainstream maintenance for PI/PO 7.5, with extended maintenance available until the end of 2030 at additional cost and with a narrower scope. SAP positions SAP Integration Suite as PI/PO's logical successor. If you want the fuller history and version comparison, see our guide on everything you need to know about SAP PI and SAP PO.
Integrated operational processes are a key component of business success today. Companies invest in SAP PI/PO because it gives them a powerful integration platform that connects different systems and applications, both internally and externally. It lets companies efficiently manage the flow of data between systems and automate processes and workflows. This reduces costs, improves performance, and increases the overall efficiency and agility of the business.
The table below summarizes the mapping types PI/PO supports.
Mapping type | What it does |
Message Mapping | Graphical mapping that converts data from one message format to another |
Java Mapping | Performs complex transformations using custom Java code |
XSLT Mapping | Transforms data from one XML format to another using XSLT stylesheets |
Graphical Mapping | Performs simple field-to-field mappings without writing code |
Content Conversion | Converts a message from one encoding format to another |
Value Mapping | Maps values from one field to corresponding values in another |
Function Library | Defines reusable functions that multiple mappings can call |
Message mapping is a feature of SAP PI/PO that converts data from one format to another. It is a graphical tool you use to match source and target fields in different structures according to your business needs. It lets you define conversions between message formats such as XML, HTML, EDI and others.
You also use message mapping to convert messages from one protocol to another, for example from HTTP to HTTPS. The tool lets you create custom maps and define rules and conditions that determine how data transforms as it moves through the interface.

Yes, for now. Mainstream maintenance for PI/PO 7.5 runs through December 31, 2027, with extended maintenance available until the end of 2030 at additional cost and reduced scope.
Message mapping is a graphical, mostly no-code tool for field-level conversions. Java mapping uses custom Java code for transformations too complex for the graphical tool to handle.
It depends on your migration timeline. With mainstream maintenance ending in 2027, many organizations now build new interfaces on SAP Integration Suite and limit PI/PO work to maintaining existing interfaces.
SAP positions SAP Integration Suite, its cloud-native integration platform on SAP BTP, as the strategic successor to PI/PO.
SAP PI/PO message mapping remains a core skill for teams running PI/PO today, but the platform's 2027 maintenance deadline should shape how much new work you build on it. Plan new interfaces with SAP Integration Suite in mind. For support with your SAP PI/PO project or migration, contact MDP Group.
