  The SAP error message ALM_ME034, which states "No key fields of middleware system in server-driven replication," typically occurs in the context of middleware systems that are used for data replication between SAP systems or between SAP and non-SAP systems. This error indicates that the system is unable to find the necessary key fields required for the replication process.
  Cause:
  
  Missing Key Fields: The key fields that are required for the replication process are not defined or are missing in the middleware configuration.
  Incorrect Configuration: The middleware system may not be properly configured to recognize the key fields from the source system.
  Data Model Changes: Changes in the data model (e.g., changes in the structure of the database tables) may lead to the absence of expected key fields.

  Define Key Fields: If key fields are missing, you may need to define them in the middleware configuration. This can often be done in the middleware's administration or configuration interface.
  Review Data Model: Check if there have been any recent changes to the data model that could affect the key fields. If changes have been made, update the middleware configuration accordingly.
  Replication Setup: Verify the setup of the server-driven replication process. Ensure that all required parameters are correctly set and that the replication process is properly configured.
  Consult Documentation: Refer to the official SAP documentation for the specific middleware you are using (e.g., SAP PI/PO, SAP Data Services) for guidance on configuring key fields and troubleshooting replication issues.
