• What is the cause and solution for SAP error message AD192 - In generic buffering you cannot select a number of key fields ?

  The SAP error message AD192 indicates that there is an issue with the configuration of generic buffering in the SAP system. This error typically arises when you attempt to define a generic buffer for a database table or view, but the selection criteria include multiple key fields, which is not allowed.
  Cause:
  The error occurs because:
  
  In SAP, generic buffering allows for the caching of data in memory to improve performance. However, it has specific rules regarding the selection of key fields.
  The system does not permit the selection of multiple key fields for generic buffering. Instead, it expects either a single key field or a combination of fields that do not include multiple key fields.
  
  Solution:
  To resolve the AD192 error, you can take the following steps:
  
  
  Review Buffering Settings:
  
  Go to the transaction code SE11 (Data Dictionary) and check the buffering settings for the relevant table or view.
  Ensure that you are not trying to buffer using multiple key fields.
  
  
  
  Modify Key Field Selection:
  
  If you need to buffer the data, consider modifying your selection criteria to use a single key field or a combination of non-key fields.
  If you require multiple fields for your application logic, you may need to implement a different approach, such as using a secondary index or adjusting your application logic to work with the available key fields.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to generic buffering to understand the limitations and best practices.
  
  
  
  Testing:
  
  After making changes, test the configuration to ensure that the error no longer occurs and that the buffering works as expected.
