• What is the cause and solution for SAP error message RSDD_ZA171 - Contact SAP support if system cannot be restarted manually ?

  The SAP error message RSDD_ZA171 typically indicates an issue related to the Data Warehousing Workbench or the data modeling environment in SAP BW (Business Warehouse). This error often arises when there is a problem with the data flow or the system's ability to restart a process or job that has failed.
  Cause:
  
  Job Failure: A data load or process chain job may have failed, leading to the system being unable to restart it automatically.
  System Configuration Issues: There may be configuration issues within the BW system that prevent proper execution of data loads or process chains.
  Locks or Deadlocks: There could be locks on certain objects or deadlocks in the system that prevent the job from being restarted.
  Data Consistency Issues: Inconsistent data or issues with the data model can also lead to this error.
  Resource Limitations: Insufficient system resources (memory, CPU) can cause jobs to fail and prevent restarts.
  
  Solution:
  
  Manual Restart: Try to manually restart the failed job or process chain from the SAP BW administration console.
  Check Logs: Review the job logs and error messages to identify the root cause of the failure. This can provide insights into what went wrong.
  Clear Locks: If there are locks on objects, you may need to clear them using transaction codes like SM12 (for lock entries) or SM21 (for system logs).
  Check Data Consistency: Use transaction codes like RSA1 to check the data model and ensure that all objects are consistent and properly configured.
  System Resources: Monitor system resources to ensure that there are enough resources available for the job to run. You may need to optimize performance or allocate more resources.
  Reconfigure Process Chains: If the issue persists, consider reconfiguring the process chains or data flows that are causing the problem.
  Contact SAP Support: If you are unable to resolve the issue through the above steps, it is advisable to contact SAP support for further assistance. Provide them with detailed logs and error messages to help diagnose the problem.
