RSCREEN_STARTSCREEN 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 "Start 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_RSCREEN_STARTSCREEN TYPE RSCREEN_STARTSCREEN.
The RSCREEN_STARTSCREEN table consists of various fields, each holding specific information or linking keys about Start screen data available in SAP. These include BUTXT (Name of Company Code or Company), ACCOUNT (Loan number), PARTNER (Business Partner Number), STORED_VERSION (Sequence Number of Saved Model Calculation)... 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. .
