ICL_VERS1_STRUCT 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 "Structure Used in Version Management" 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_ICL_VERS1_STRUCT TYPE ICL_VERS1_STRUCT.
The ICL_VERS1_STRUCT table consists of various fields, each holding specific information or linking keys about Structure Used in Version Management data available in SAP. These include ACTIVE (Status), CHANGEDBY (Version Created By (= Object Changed By)), CHANGETIME (Version Created: Date + Time), INACTIVETIME (Version Deactivated: Date + Time)... 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. .
