DPR_TS_OBJLINK 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 "External Structure + Reference" 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_DPR_TS_OBJLINK TYPE DPR_TS_OBJLINK.
The DPR_TS_OBJLINK table consists of various fields, each holding specific information or linking keys about External Structure + Reference data available in SAP. These include GUID (UUID in X form (binary)), OBJECT_TYPE (Type of Linked Object), CATEGORY (Category of Object Type in Object Link), OBJECT_TYPE_TEXT (Description of Object Type)... 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. .
