• What is the cause and solution for SAP error message WS_TOOL235 - Service definition &1 must no be changed (ZDM Upgrade running) ?

  The SAP error message:
  WS_TOOL235 Service definition &1 must not be changed (ZDM Upgrade running)
  
  Cause:
  This error occurs because a ZDM (Zero Downtime Maintenance) upgrade is currently running in the system. During a ZDM upgrade, certain service definitions are locked to prevent changes that could interfere with the upgrade process. The system detects an attempt to modify a service definition (indicated by &1, which is the service name) that is currently protected due to the ongoing upgrade.
  Explanation:
  
  ZDM Upgrade is a process used to upgrade SAP systems with minimal downtime.
  During this process, SAP locks certain objects, including service definitions, to maintain system stability and consistency.
  Any attempt to change these locked service definitions results in the WS_TOOL235 error.
  
  
  Solution:
  
  
  Wait for the ZDM upgrade to complete:
  The simplest and safest approach is to wait until the upgrade process finishes. After completion, the locks on the service definitions will be released, and changes can be made.
