SAP Message BRAIN230 - Could not buffer query structures. Buffer too small

Diagnosis
To improve the runtime, the structures needed by the OLAP engine arestored in the shared memory. This query requires &V1& bytes. This ismore space than is available in the shared memory.

Procedure for System Administration
Make sure that the value (in KB) of the profile parameterrsdb/obj/buffersize is 4.5 times larger than the space requiredby this query. For information on this parameter, see transaction RZ11.However, remember that for performance reasons an individual object cannot occupy the majority of the buffer, so the maximum permitted objectsize is considerably less that the total size of the buffer.
If you do not increase the parameter, the necessary structures must beread from the database.
