DB2QJST SAP (log manager statitics block) Structure details
Description: log manager statitics block
Structure field list including key, data, relationships and ABAP select examples
DB2QJST 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 "log manager statitics block" 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_DB2QJST TYPE DB2QJST.
The DB2QJST table consists of various fields, each holding specific information or linking keys about log manager statitics block data available in SAP. These include QJSTLL (Small integer (2 bytes)), QJSTEID (Field type char, length 4), QJSTWRW (Field Type INT, Length 4), QJSTWRNW (Number of Write-No-Wait Requests).. 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. .
