In a generically buffered table or view, access to nonexistent data is very fast (see Buffer Management).When using generic buffering, any ABAP SQL statements must respect the generic key to prevent them from bypassing table buffering.Generic buffering should be used if usually only certain areas...
Full buffering Note If generic buffering or full buffering is activated, and the database table or view is specified statically in an ABAP SQL statement, the secondary indexes of the table are not ignored when the data is read from the table buffer. If single record buffering is used, only...
ABAP 支持下列几种缓冲类型: 当使用完全缓冲(full bufferred)时,要么缓冲整个表,要么不缓冲任何记录。 当访问单个记录时,该表的整个数据/记录都会被缓冲。 缓冲是指所有记录都在缓冲表中。 完全缓冲适应于频繁读取但是极少写入的数据库表。 当使用 Generic Buffering 时,所有带有 Generic 键的记录都会被一次性缓冲。
SAP Managed Tags: ABAP Development Hi, With Bypassing Buffer... both the warings are gone. But, Why these warings are came even Buffering is swithed off for CSKT table. and, Which is the select statement to avoid these errors. Thanks, --Naveen Inuganti. Reply Former Member ...

When one is creating programs it is important to keep in mind that if data is buffered, and this buffered data is subsequently read, it may not always be up to date. So, when tables are created, they must be created in such a way that the system is told that buffering can or cannot...
Buffered Table TVGRT in a JOIN 1 BufferedTableTVGRTinaJOIN 去SE11查看了表TVGRT的技术设置,果然是个buffered表, 又搜了一些资料如下: SAP Buffering When accessing database tables using Open SQL, SAP buffering is effective as standard if it is activated for the corresponding database table. It can...
Alternatively, you can use one of the views in the ABAP Dictionary to select data. If you do use a view, the SAP buffering is switched off. You should use the aggregate functions rather than selecting data and grouping it yourself. SAP buffering is switched off when you use aggregate ...
If the row is not found, this is noted in the buffer and a fully specified WHERE clause is used to avoid a new database access in the next read. Notes When using single record buffering, any ABAP SQL statements must respect the full primary key to prevent them from bypassing table ...
