ARSTR 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 "Structure for Analysis Report" 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_ARSTR TYPE ARSTR.
The ARSTR table consists of various fields, each holding specific information or linking keys about Structure for Analysis Report data available in SAP. These include FCFC1 (Customizing billing types for error analysis), FCPC1 (Customizing Pricing), ICKC1 (Customizing Copy Control for Information Analysis), ICFC1 (Customizing Billing Types for Information Analysis_)... 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. .
