BAPI_TS_DESCRIPTION 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 "Long Text with Language" 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_DESCRIPTION TYPE BAPI_TS_DESCRIPTION.
The BAPI_TS_DESCRIPTION table consists of various fields, each holding specific information or linking keys about Long Text with Language data available in SAP. These include DESCRIPTION_LINE (Long Text Line for BAPI Interface Output)... 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. .
