RMODEL_VERSIONS 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 "Model Calculations" 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_RMODEL_VERSIONS TYPE RMODEL_VERSIONS.
The RMODEL_VERSIONS table consists of various fields, each holding specific information or linking keys about Model Calculations data available in SAP. These include PRODUCT_ID (Internal Product ID), PRODUCT_VERSION (Product Version), VDARL (), MANDT (Client)... 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. .
