LVC_DEREF SAP (liveCache: OMS Monitor Structure (Accesses to Obj Instances)) Structure details
Description: liveCache: OMS Monitor Structure (Accesses to Obj Instances)
Structure field list including key, data, relationships and ABAP select examples
LVC_DEREF 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 "liveCache: OMS Monitor Structure (Accesses to Obj Instances)" 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_LVC_DEREF TYPE LVC_DEREF.
The LVC_DEREF table consists of various fields, each holding specific information or linking keys about liveCache: OMS Monitor Structure (Accesses to Obj Instances) data available in SAP. These include CALL_CNT (Number of database procedure calls), SUM_RTIME (Total Runtime for All Calls (AvgRuntime * CallCnt)), OMS_DEREF (Number of dereferencings (accesses to object instances)), LC_DEREF (No. of dereferencings with liveCache basis layer).. 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. .
