AD01STRCOM 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 about structuring fields and field name" 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_AD01STRCOM TYPE AD01STRCOM.
The AD01STRCOM table consists of various fields, each holding specific information or linking keys about Information about structuring fields and field name data available in SAP. These include FILTPRIO (Sequence for Structuring Dynamic Items), FILTSETCL (Set class), FILTSETTAB (Table for set), FILTSETNR (Set 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. .
