MSSCOLLCOUNTERS SAP (Collection of key performance counters displayed in ST04) Structure details
Description: Collection of key performance counters displayed in ST04
Related tables to MSSCOLLCOUNTERS
Access table MSSCOLLCOUNTERS
Structure field list including key, data, relationships and ABAP select examples
MSSCOLLCOUNTERS 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 "Collection of key performance counters displayed in ST04" 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_MSSCOLLCOUNTERS TYPE MSSCOLLCOUNTERS.
The MSSCOLLCOUNTERS table consists of various fields, each holding specific information or linking keys about Collection of key performance counters displayed in ST04 data available in SAP. These include IOSTALLREADSRV (IOStall per read request), IOSTALLWRITESRV (IOStall per read request), IOSTALLREADDB (IOStall per read request), IOSTALLWRITEDB (IOStall per read request).. 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. .
