• What is the cause and solution for SAP error message ISLM_API274 - Zero downtime maintenance in process; only display operations possible ?

  The SAP error message ISLM_API274 indicates that a zero downtime maintenance (ZDM) process is currently active. This means that the system is in a state where only display operations are allowed, and no changes can be made to the system until the ZDM process is completed.
  Cause:
  The error occurs when:
  
  A zero downtime maintenance operation is initiated, which is designed to allow for system updates without significant downtime.
  During this process, the system restricts certain operations to ensure data consistency and integrity.
  Users attempt to perform operations that modify the system (like updates or changes) while the ZDM process is still running.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check ZDM Status: Use transaction codes like SMD (SAP Solution Manager Diagnostics) or S4HANA to check the status of the ZDM process. You can also check the logs for any ongoing maintenance activities.
  
  
  Wait for Completion: If you find that a ZDM process is indeed running, you will need to wait until it completes. The duration of the process can vary based on the complexity of the maintenance being performed.
  
  
  Contact Basis Team: If the ZDM process seems to be stuck or taking longer than expected, contact your SAP Basis team or system administrator. They can investigate the logs and determine if any issues are causing the delay.
  
  
  Review Documentation: Refer to SAP documentation or notes related to zero downtime maintenance for specific guidance on handling issues related to ZDM.
  
  
  Perform Display Operations: While the ZDM process is active, you can still perform display operations. This allows you to view data without making changes.
