• What is the cause and solution for SAP error message KH878 - Too many line items (costing-based/current) ?

  The SAP error message KH878 ("Too many line items (costing-based/current)") typically occurs in the context of costing-based profitability analysis (CO-PA) when the system encounters a limit on the number of line items that can be processed or displayed. This can happen during various operations, such as reporting or data retrieval, where the volume of data exceeds the system's predefined thresholds.
  Cause:
  
  Excessive Data Volume: The error is primarily caused by attempting to process or display a large number of line items in costing-based CO-PA. SAP has limits on the number of line items that can be handled in a single query or report.
  Configuration Settings: The system may have specific configuration settings that limit the number of line items that can be processed at once.
  Performance Issues: High data volume can lead to performance issues, causing the system to restrict the number of line items to ensure stability and performance.
  
  Solution:
  
  Filter Data: Reduce the number of line items by applying filters to your report or query. This can include narrowing down the date range, specific characteristics, or other relevant criteria to limit the data set.
  Use Aggregated Reports: Instead of detailed line item reports, consider using aggregated reports that summarize the data, which can help avoid hitting the line item limit.
  Adjust Configuration: If you have the necessary permissions, you can check and adjust the configuration settings related to line item limits in the CO-PA module. Consult with your SAP Basis or CO-PA configuration team for assistance.
  Batch Processing: If applicable, consider processing the data in smaller batches rather than attempting to retrieve all line items at once.
  Performance Optimization: Work with your SAP Basis team to optimize the performance of your system, which may involve database tuning or adjusting system parameters.
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling large data sets in CO-PA.
  Documentation: Review SAP documentation related to CO-PA and line item processing limits for more detailed information on best practices and system capabilities.
