FMDERIVE_GROUPS 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 "Infos about SETs in tables for rules" 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_FMDERIVE_GROUPS TYPE FMDERIVE_GROUPS.
The FMDERIVE_GROUPS table consists of various fields, each holding specific information or linking keys about Infos about SETs in tables for rules data available in SAP. These include GROUP (Set data element), ELEM (Data element for the content of a Set), NAME_FROM (Field Name), NAME_TO (Field Name)... 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. .
