The structure of the intervals of a number range object is defined in database tableNRIV. If a number is taken from an interval, the table line for it must be locked. This lock remains until the application that requested the number is closed, either with aCOMMIT WORKor aROLLBACK. Only...
In a generically buffered table or view, access to nonexistent data is very fast (see Buffer Management).When using generic buffering, any Open SQL statements must respect the generic key to prevent them from bypassing SAP buffering.Generic buffering should be used if usually only certain areas ...
SAP buffering Takes data from database tables defined in ABAP Dictionary and buffers it in a table buffer in the shared memory of the current application server. The definition determines whether and how a database table is buffered. Buffering usually improves performance significantly (by factors ...
How large is the buffered part (the generic region) of the table? If in doubt, use the following guidelines: You should buffer tables that are mostly read and rarely modified. Buffering is recommended for small tables. Large tables are usually indexed by the database, whereas the table buffe...
