TPL_ENV_USAGE 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 "CO-ABC: Application Screen in Template Environmt Maintenance" 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_TPL_ENV_USAGE TYPE TPL_ENV_USAGE.
The TPL_ENV_USAGE table consists of various fields, each holding specific information or linking keys about CO-ABC: Application Screen in Template Environmt Maintenance data available in SAP.
