BAPI_TS_GUID 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 "Collection of All GUIDs for BAPI Interface" 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_GUID TYPE BAPI_TS_GUID.
The BAPI_TS_GUID table consists of various fields, each holding specific information or linking keys about Collection of All GUIDs for BAPI Interface data available in SAP. These include TEMPLATE_GUID (GUID for Template Object to Be Copied in BAPI Interface), PROJECT_DEFINITION_GUID (GUID for Project in BAPI Interface), PROJECT_TEMPLATE_GUID (GUID for Project Template in BAPI Interface), PHASE_GUID (GUID for Phase in BAPI Interface)... 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. .
