Summary :
To facilitate client copies and system planning in SAP, accurate determination of client or table sizes is crucial, especially due to the substantial size variability in productive environments. For local or remote client copies, post-test run tablespace analysis in logs is recommended to estimate required memory space, supplemented by reports like RSSPACECHECK and RSTABLESIZE for further memory requirements assessment. Notably, table compression affects size estimation accuracy, with transaction DB02 or database tools advisable for verifying estimations. For detailed sizing, reports YSTABSIZ or the corresponding ZSTABSIZ for earlier releases provide insights into table size distribution and memory usage, considering row width and count.
