• What is the cause and solution for SAP error message CMM_TRM_DEND406 - Cannot determine snapshot time for PH/Node combination and eval. date ?

  The SAP error message CMM_TRM_DEND406 indicates that the system is unable to determine a snapshot time for a specific combination of a physical host (PH), node, and evaluation date. This error typically arises in the context of SAP's Capacity Management or similar modules where historical data snapshots are required for analysis.
  Causes:
  
  
  Missing Data: The most common cause is that there are no available snapshots for the specified physical host and node combination on the given evaluation date. This could happen if data collection was not configured properly or if the data was not recorded for that period.
  
  
  Incorrect Configuration: The configuration settings for data collection or the evaluation might be incorrect, leading to the inability to retrieve the necessary data.
  
  
  Time Frame Issues: The evaluation date might fall outside the range of available snapshots, either because the data retention period has expired or because the snapshots were not created for that time frame.
  
  
  System Errors: There could be underlying system issues or bugs that prevent the retrieval of snapshot data.
  
  
  Solutions:
  
  
  Check Data Availability: Verify if there are snapshots available for the specified PH/Node combination and the evaluation date. You can do this by checking the relevant database tables or using transaction codes related to capacity management.
  
  
  Review Configuration: Ensure that the configuration for data collection is set up correctly. This includes checking the settings for the data sources and ensuring that the data is being collected as expected.
  
  
  Adjust Evaluation Date: If possible, try using a different evaluation date that is known to have available snapshots. This can help determine if the issue is related to the specific date.
  
  
  Data Retention Settings: Review the data retention settings in your SAP system to ensure that snapshots are being retained for the necessary duration.
  
  
  System Logs: Check system logs for any errors or warnings that might provide additional context about the issue. This can help identify if there are any underlying system problems.
