CTM_ADMIN 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 "Creation and Change Data for Context 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_CTM_ADMIN TYPE CTM_ADMIN.
The CTM_ADMIN table consists of various fields, each holding specific information or linking keys about Creation and Change Data for Context Management data available in SAP. These include FDATE (Creation Date), FTIME (Creation Time), FRELEASE (Release of SAP System), LUSER (Last Changed By)... 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. .
