RMODEL_CHANGED_CONDITIONS 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 "Condition Fields Changed from User Interface" 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_CHANGED_CONDITIONS TYPE RMODEL_CHANGED_CONDITIONS.
The RMODEL_CHANGED_CONDITIONS table consists of various fields, each holding specific information or linking keys about Condition Fields Changed from User Interface data available in SAP. These include FIELDNAME (ALV control: Field name of internal table field), ALV_FIELDNAME (ALV control: Field name of internal table field), TEXT (Medium Field Label)... 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. .
