This is a snapshot of the current (percentage and absolute values in kilobytes) and the maximum memory usage of the various
SAP memory types. The table also indicates whether, and to what extent, the requirement is satisfied from the main memory and from the disk.You can determine from the row
Extended Memory that the SAP Extended Memory is sufficiently large. The value [Max. use] is, in this example, noticeably smaller than the created memory area [In memory]. If both values are identical, you must increase the extended memory (profile parameter: em/initial_size_MB).See also:
