• What is the cause and solution for SAP error message /SAPAPO/CTM1838 - Planning explanation data cannot be saved due to maximum limit of 2GB ?

  The SAP error message /SAPAPO/CTM1838 indicates that the planning explanation data cannot be saved because it has reached the maximum limit of 2GB. This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when the system attempts to store or process planning data that exceeds the size limit.
  Cause:
  
  Data Volume: The primary cause of this error is the volume of planning explanation data generated during the planning process. If the data generated exceeds 2GB, the system will not be able to save it.
  Configuration Settings: Certain configuration settings in the APO system may lead to excessive data generation, such as detailed logging or extensive planning runs.
  Inefficient Planning Runs: Running planning processes that generate a large amount of data without proper filtering or aggregation can lead to this issue.
  
  Solution:
  
  
  Data Management:
  
  Reduce Data Volume: Review the planning runs and try to limit the amount of data being generated. This can be done by filtering out unnecessary data or by adjusting the planning parameters.
  Archiving: Implement data archiving strategies to remove old or unnecessary planning data from the system, thereby freeing up space.
  
  
  
  Configuration Adjustments:
  
  Adjust Planning Settings: Check the configuration settings in the APO system to see if you can reduce the level of detail in the planning explanation data. This may involve changing settings related to logging or the level of detail captured during planning runs.
  Use Aggregated Data: If possible, use aggregated data for planning instead of detailed data to minimize the volume of explanation data generated.
  
  
  
  System Upgrade: If the issue persists and is a frequent problem, consider discussing with your SAP Basis team about upgrading your system or exploring options for increasing the data storage limits, if applicable.
  
  
  Monitoring and Alerts: Set up monitoring and alerts for data volume thresholds to proactively manage the size of planning explanation data and avoid hitting the limit.
