Summary :
This SAP Note addresses performance issues due to unbuffered accesses on the NRIV table, leading to significant system delays and potential hangs. The problem originates from applications performing direct database locks on NRIV intervals, obstructing additional number retrievals and thereby serializing operations. The solution includes identifying the problematic number range objects via procedures outlined in reference Note 572905 and considering buffer implementations from Note 504875. For countries with legal sequential numbering requirements, alternative buffering strategies must be evaluated carefully. Developers should avoid modifications to standard SAP-delivered number range objects unless guided by specific SAP Notes.
