TAB_CSCR 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 "Settings for a tab page in the flexible detail screen" 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_TAB_CSCR TYPE TAB_CSCR.
The TAB_CSCR table consists of various fields, each holding specific information or linking keys about Settings for a tab page in the flexible detail screen data available in SAP. These include ERSTE (Indicator: First tab page), SUB1 (Detail screen 1), SUB1_T (Short Description of Repository Objects), SUB2 (Detail screen 2)... 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. .
