  • What causes this issue?

    Usually all the data, which is required to run a search query and which
    is generated when a search query is run<(>,<)> is stored uncompressed in
    the shared memory of the application server. This improves the
    performance of the BW search in the SAP HANA application when the search
    is called multiple times.
    Currently the BW search on the SAP HANA application cannot store all the
    generated data required in the shared memory of the application server
    in uncompressed format. This forces the application to compress the data
    before writing to the shared memory of the application server.

    System Response

    The performance of the search query might be slowed, because reading
    compressed data from the shared memory of the application server takes
    longer than reading uncompressed data.

    How to fix this error?

    The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

    Procedure for System Administrators

    The application buffer can be filled to an internal maximum limit, which
    can be adjusted using the profile parameter rsdb/obj/buffersize (SHARED
    BUFFER).

This typically occurs when the buffer size allocated for the application is too small to handle the volume of data being processed, leading to slower search operations.
    
    Cause: Insufficient Buffer Size: The application buffer memory is not adequately sized to handle the data being processed, which can lead to performance issues. High Data Volume: A large volume of data being searched can overwhelm the existing buffer size.
    Configuration Issues: The system may not be optimally configured for the specific workload or data access patterns.
    Solution: Increase Buffer Size: You can increase the size of the application buffer memory. This is typically done in the SAP system configuration settings. Navigate to the transaction code RZ10 (Profile Parameter Maintenance) and look for parameters related to buffer sizes, such as abap/buffersize or rsdb/ntab_size.
