TST04INF64 SAP (Statistics: Structure for Database Information Display) Structure details
Dictionary Type: Structure
Description: Statistics: Structure for Database Information Display
Description: Statistics: Structure for Database Information Display
Structure field list including key, data, relationships and ABAP select examples
TST04INF64 is a standard SAP Structure so does not store data like a database table does. It can be used to define the fields of other actual tables or to process "Statistics: Structure for Database Information Display" Information within sap ABAP programs.
This is done by declaring abap internal tables, work areas or database tables based on this Structure. These can then be used to store and process the required data appropriately.
i.e. DATA: wa_TST04INF64 TYPE TST04INF64.
The TST04INF64 table consists of various fields, each holding specific information or linking keys about Statistics: Structure for Database Information Display data available in SAP. These include BUFREADS (Number of reads from shared memory buffer), DSKREADS (Actual reads (I/O requests) from disk), BUFWRITES (Number of writes to shared memory buffer), DSKWRITES (Actual number of writes (I/O requests) to disk).. See below for full list along with technical details, documentation, text table, check tables, foreign key relationships, conversion routines, relevant tcodes and example ABAP select code etc. .
