RMSTS_INFORMATION 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 "Information Text for Log" 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_RMSTS_INFORMATION TYPE RMSTS_INFORMATION.
The RMSTS_INFORMATION table consists of various fields, each holding specific information or linking keys about Information Text for Log data available in SAP. These include INFORM_LINE (Information About Calculation Log)... 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. .
