RINTER_FLD_ATTR 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 "Field Attributes" 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_RINTER_FLD_ATTR TYPE RINTER_FLD_ATTR.
The RINTER_FLD_ATTR table consists of various fields, each holding specific information or linking keys about Field Attributes data available in SAP. These include FLDNAME (Field Name), FLDSTATUS (Status of dynpro field (+,-, ., *)), GRUP (Modification group 1)... 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. .
