CMP_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 Date, Generic Comparison Tool" 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_CMP_ADMIN TYPE CMP_ADMIN.
The CMP_ADMIN table consists of various fields, each holding specific information or linking keys about Creation and Change Date, Generic Comparison Tool data available in SAP. These include FTIMESTAMP (UTC Time Stamp in Short Form (YYYYMMDDhhmmss)), LUSER (User Name), LTIMESTAMP (UTC Time Stamp in Short Form (YYYYMMDDhhmmss))... 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. .
