This value specifies the size of the SAP paging file in 8 KB blocks. The paging file functions as memory for extracts and exports to memory.
See also: SAP Paging.
The default value is platform-specific and is determined dynamically. The default value is specified in transaction RZ11. This value should not normally be changed.
Problems should not occur even if the size of the paging file is large. You just need to ensure there is enough space in the file system.
