Summary :
This SAP Note addresses performance issues related to number range objects (SNUM, SNRO) due to inappropriate buffering settings. It details two buffering techniques: main memory and local buffering with Work Process ID (from Release 4.0B). Main memory buffering is suited for scenarios without legal restrictions on number assignments and involves locks on the NRIV table for new buffer requests, beneficial for performance but may cause numbered gaps. Local buffering with Work Process ID is the alternative when main memory buffering isn't feasible, supporting gap documentation and preventing chronological numbering irregularities. It is emphasized that optimal buffer size varies by application process demands.
