BAPI_TS_CHECKLIST 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 "BAPI CREATE/CHANGE: Checklist Header Fields" 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_BAPI_TS_CHECKLIST TYPE BAPI_TS_CHECKLIST.
The BAPI_TS_CHECKLIST table consists of various fields, each holding specific information or linking keys about BAPI CREATE/CHANGE: Checklist Header Fields data available in SAP. These include CHECKLIST_NAME_LANGUAGE (External Language Key), CHECKLIST_NAME (Project Element Name), CHECKLIST_TYPE (Checklist Type), SORT_NUMBER (Sort Number)...
