How to fix this error?

Procedure for System Administrators

Make sure that the value (in KB) of the profile parameter
<AB>rsdb/obj/buffersize</> is 4.5 times larger than the space required
by this query. For information on this parameter, see transaction RZ11.
However, remember that for performance reasons an individual object can
not occupy the majority of the buffer, so the maximum permitted object
size is considerably less that the total size of the buffer.
If you do not increase the parameter, the necessary structures must be
read from the database.
