RTOTYP 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 "Data Elements for Runtime Object Types" 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_RTOTYP TYPE RTOTYP.
The RTOTYP table consists of various fields, each holding specific information or linking keys about Data Elements for Runtime Object Types data available in SAP. These include RTOSC (Production Data Structure for PP/DS Subcontracting), RTOXX (Production Data Structure Type), RTOSN (SNP Production Data Structure), RTOSS (Production Data Structure for SNP Subcontracting)... 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. .
