• What is the cause and solution for SAP error message RSPLF091 - Execution mode: In-Memory ?

  The SAP error message RSPLF091 typically relates to issues encountered when executing a query in the SAP BW (Business Warehouse) environment, particularly when using the In-Memory execution mode. This error can arise due to various reasons, including configuration issues, data model problems, or resource limitations.
  Cause
  
  In-Memory Configuration Issues: The In-Memory engine may not be properly configured or may not have sufficient resources allocated.
  Data Model Problems: There could be issues with the data model, such as missing or incorrect data, which can prevent the query from executing properly.
  Resource Limitations: The system may not have enough memory or processing power to handle the query execution in In-Memory mode.
  Query Design Issues: The query itself may be poorly designed, leading to inefficiencies or errors during execution.
  
  Solution
  
  Check Configuration: Ensure that the In-Memory engine is correctly configured. This includes checking the settings in the SAP BW system and ensuring that the necessary components are activated.
  Review Data Model: Validate the data model used in the query. Check for any inconsistencies or missing data that could be causing the error.
  Monitor System Resources: Use transaction codes like ST02 (Tune Summary) or ST06 (Operating System Monitor) to monitor memory usage and system performance. If resources are low, consider optimizing the system or increasing the available resources.
  Optimize Query Design: Review the query design for inefficiencies. Simplifying the query or breaking it into smaller parts may help in executing it successfully.
  Fallback to Other Execution Modes: If the In-Memory execution mode continues to cause issues, consider switching to a different execution mode (like OLAP or Classic mode) as a temporary workaround.
