A pattern is visible in how mid-market SAP organizations are approaching the December 2027 SAP IDM maintenance deadline. 

The evaluation starts. Three options get compared: SAP GRC for HANA 2026, a large enterprise IGA vendor, and potentially a purpose-built mid-market platform. The comparison framework focuses on SAP coverage, brand recognition, and cost. The enterprise IGA vendor has the most comprehensive capability set. SAP GRC is the familiar path. The mid-market platform is underweighted because it is less well-known. 

The decision gets made. Then eighteen months later the compliance team starts asking why the governance posture looks the same as it did under SAP IDM — or why the implementation is still not complete. 

The framework is the problem. 

What the evaluation is missing 

The standard comparison of SAP IDM replacement options focuses on capabilities. The comparison that produces the right decision focuses on three things the capability comparison misses. 

The first is prerequisites. SAP GRC for HANA 2026 requires SAP HANA database and S/4HANA Foundation as prerequisites. Organizations on non-HANA databases face an additional database migration before upgrading to GRC 2026. That is not one migration, it is two sequential migrations. The timeline implication is significant and is frequently not surfaced until after the evaluation is complete. 

The second is team fit. Enterprise IGA platforms are designed for organizations with dedicated IAM teams and 12 to 18 month implementation budgets. For a mid-market organization without a dedicated IAM function, the capability set is comprehensive and the implementation complexity frequently exceeds the team's capacity to operationalize it. A capable platform that is underutilized because the implementation exceeded the team's bandwidth is not a compliance success. 

The third is governance scope. SAP IDM governed the SAP boundary. SAP GRC for HANA 2026 governs the SAP boundary. An evaluation that starts from SAP IDM parity will select a replacement that replicates the existing governance scope. Organizations that also run Microsoft 365, ServiceNow, Salesforce, and Workday alongside SAP have a governance gap that extends beyond the SAP boundary. The migration is the right moment to close that gap, not to replicate it. 

What SAP IDM actually left ungoverned 

SAP IDM provisioned access based on roles. It did not detect whether the combination of roles a user holds creates a Segregation of Duties violation. It did not govern access to any system outside SAP. It produced no cross-system access visibility and generated no SoD detection capability. Organizations that have been running SAP IDM for a decade have been running a governance architecture that was never designed to catch the conflicts auditors most commonly cite. 

The migration from SAP IDM is an upgrade opportunity. Evaluations that frame the decision as replacing like-for-like are leaving that opportunity on the table. 

The timeline math 

SAP IDM mainstream maintenance ends December 31, 2027. A purpose-built mid-market replacement deploys in 6 to 12 weeks. Evaluation and procurement typically adds 4 to 8 weeks. An organization starting its evaluation now completes the migration in early 2027, with a full audit cycle on the new platform before the deadline. 

An organization that treats this as a 2027 problem completes the migration under pressure, at or after the deadline, without audit runway. 

The difference in outcome is significant. The difference in effort to avoid it is starting the evaluation in 2026 rather than 2027. 

What path are organizations currently running SAP IDM leaning toward, and what is driving the decision? The experiences of teams mid-evaluation would be worth hearing.
