Summary :
Transaction ST02 indicates increased swaps in the export/import buffer commonly used by the ABAP List Viewer (ALV) for performance improvements, retained until system shutdown. Problems arise when multiple apps compete for buffer resources or when the buffer size is insufficient, leading to excessive loading and object displacement. To mitigate, assess 'Swaps' total since system start and check buffer hit ratio with ST02—it should exceed 80%. If not, examine buffer settings using 'rsdb/obj/buffersize' for size adjustments, ensuring at least 10% free space, and 'rsdb/obj/max_objects' for managing object counts. Changes necessitate system restart and post-adjustment monitoring.
