SAP has announced that 2027 is the deadline for mainstream maintenance support for its Business Suite 7 core applications, including the widely-used ECC 6.0. This announcement has significant implications for finance leaders who rely on these systems for their critical operations. This isn't just an IT issue; it's a strategic imperative that demands immediate attention from finance executives. In this post, we'll break down what this deadline means for finance, why it matters, and what actionable steps finance leaders should take to ensure a smooth transition to S/4HANA.

what happened

SAP has officially stated that mainstream maintenance support for SAP ECC will end in 2027. This means that after this date, SAP will no longer provide regular updates, patches, or new functionalities for the ECC platform. While extended support options may be available at a higher cost, relying on an unsupported system introduces substantial risks for organizations.

This announcement isn't new, but the urgency is increasing as the deadline approaches. Many organizations are still in the early stages of planning their migration. Given that S/4HANA migrations can take 18-24 months or longer, the time to act is now.

Why This Matters to Finance Leaders

The 2027 deadline is particularly critical for finance leaders because:

  • Financial Risk: Unsupported ECC systems are more vulnerable to security breaches, potentially compromising sensitive financial data. They may also fail to meet evolving regulatory requirements, leading to compliance issues.
  • Operational Inefficiency: Lack of updates hinders operational efficiency and the ability to integrate with modern technologies.
  • Strategic Disadvantage: Remaining on ECC limits access to innovation and can hinder a company's ability to compete.
  • Finance Transformation: S/4HANA offers an opportunity to transform the finance function, enabling real-time insights, process automation, and improved decision-making. Missing the migration means missing out on these advancements.

what’s happening now/next

Organizations are now actively evaluating their options and planning their S/4HANA migrations. Key activities include:

  • Strategic Planning: Finance leaders are working with IT to develop comprehensive migration strategies that align with business objectives.
  • Budget Allocation: Securing the necessary budget and resources for the migration project.
  • Partner Selection: Many organizations are partnering with experienced consultants to guide the migration process.
  • Data Preparation: Finance teams are focusing on data cleansing and harmonization to ensure a smooth transition to S/4HANA.

What this means for you

For finance leaders, the SAP ECC 2027 deadline means:

  • Urgent Action is Required: Procrastination is no longer an option. Finance leaders must prioritize S/4HANA migration to mitigate risks and capitalize on opportunities.
  • Strategic Leadership: Finance must take a leading role in the migration, working closely with IT and other departments.
  • Transformation, Not Just Upgrade: The migration should be viewed as an opportunity to transform finance operations and drive greater value for the business.

what you can/could/should do now

Finance leaders should take the following actions:

  • Assess your current landscape: Conduct a thorough assessment of your existing SAP environment and its impact on finance.
  • Develop a data strategy: Prioritize data cleansing, harmonization, and governance.
  • Plan for process optimization: Evaluate current workflows and identify opportunities to streamline and standardize processes in S/4HANA.
  • Engage with experts: Consider partnering with experienced consultants to support the migration.

The SAP ECC 2027 deadline is a critical event for finance leaders. It's a call to action to modernize financial systems, mitigate risks, and embrace the transformative potential of S/4HANA.
