DPR_TS_DETAIL_FIELDS 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 "Additional Fields That Can Be Displayed in CATS" 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_DETAIL_FIELDS TYPE DPR_TS_DETAIL_FIELDS.
The DPR_TS_DETAIL_FIELDS table consists of various fields, each holding specific information or linking keys about Additional Fields That Can Be Displayed in CATS data available in SAP. These include ACTUAL_FIELD_VALUE (Character field, length 64), FIELD_LABEL (Text (20 Characters)), IS_CHANGEABLE (Data element for domain BOOLE: TRUE (='X') and FALSE (=' ')), FIELD_LENGTH (Length (No. of Characters))...
