• What is the cause and solution for SAP error message BRAIN_DEV087 - Data integrity modes 1, 3, 9 not possible with cache usage mode 'S' ?

  The SAP error message BRAIN_DEV087 indicates that there is a conflict between the data integrity mode settings and the cache usage mode in your SAP system. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA environments when there are inconsistencies in the configuration of data processing modes.
  Cause:
  The error occurs when the system is configured to use certain data integrity modes (1, 3, or 9) that are not compatible with the cache usage mode set to 'S' (which usually stands for "Shared" or "Single"). The data integrity modes dictate how data is processed and validated, while the cache usage mode determines how data is cached and accessed.
  Data Integrity Modes:
  
  Mode 1: Data integrity mode that ensures strict data consistency.
  Mode 3: Data integrity mode that allows for some level of data inconsistency for performance reasons.
  Mode 9: A specific mode that may involve complex data processing rules.
  
  Cache Usage Modes:
  
  'S' (Shared): Indicates that the cache is shared among multiple users or processes, which can lead to potential data integrity issues if not managed correctly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Configuration Settings:
  
  Review the settings for data integrity modes and cache usage modes in your SAP BW or HANA configuration.
  Ensure that the data integrity mode you are trying to use is compatible with the cache usage mode.
  
  
  
  Change Cache Usage Mode:
  
  If you need to use data integrity modes 1, 3, or 9, consider changing the cache usage mode from 'S' to a mode that is compatible with those integrity modes. This may involve setting it to 'N' (No Cache) or another appropriate mode.
  
  
  
  Adjust Data Integrity Mode:
  
  If changing the cache usage mode is not feasible, consider adjusting the data integrity mode to one that is compatible with the current cache usage mode.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation for your specific version to understand the implications of changing these settings and to find the best practices for your scenario.
  
  
  
  Testing:
  
  After making changes, conduct thorough testing to ensure that the system behaves as expected and that data integrity is maintained.
  
  
  
  Seek Support:
