3459498 - Buffering Number Range for Purchase Requisitions


There are gaps in the material document number range and the internal number assignment of material documents is not continuous or it has buffering number range for Purchase Requisitions.




Standard system behaviour.


To improve the performance of the system, most application number ranges are buffered on the application servers. Otherwise, every number would have to be fetched from the database server by the application server in sequence, via the network, which can be very detrimental to performance.

In a busy system there could be many lock conflicts without buffering. In the cloud environment this is always the case, and the parallel buffering of PR is delivered content.
