• What is the cause and solution for SAP error message SAI_CACHE804 - No authorization to perform complete cache refresh ?

  The SAP error message SAI_CACHE804 indicates that a user does not have the necessary authorization to perform a complete cache refresh in the SAP system. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA environments where caching mechanisms are used to improve performance.
  Cause:
  The primary cause of this error is a lack of appropriate authorizations assigned to the user trying to execute the cache refresh. The specific authorization object that is usually involved in this scenario is S_RS_AUTH or other related authorization objects that control access to data warehousing and reporting functionalities.
  Solution:
  To resolve the SAI_CACHE804 error, you can follow these steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to analyze the authorization check. This will show you which specific authorizations are missing.
  Alternatively, you can use transaction code SU01 to view the user’s profile and check the assigned roles.
  
  
  
  Assign Necessary Roles:
  
  If the user lacks the required authorizations, you will need to assign the appropriate roles that include the necessary authorizations for cache refresh operations.
  Common roles that might be required include those related to data administration, data modeling, or specific roles for BW or HANA administration.
  
  
  
  Modify Authorization Profiles:
  
  If the existing roles do not provide the necessary authorizations, you may need to modify the authorization profiles or create a new role that includes the required authorizations.
  
  
  
  Consult with Security Team:
  
  If you do not have the necessary permissions to change roles or authorizations, consult with your SAP security team or administrator to ensure that the user is granted the appropriate access.
  
  
  
  Testing:
  
  After making changes to the user’s authorizations, have the user attempt the cache refresh again to verify that the issue has been resolved.
  
  
  
  Related Information:
