SIMAINFOCRTVAR 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 "IO Information About Account Creation Variant" 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_SIMAINFOCRTVAR TYPE SIMAINFOCRTVAR.
The SIMAINFOCRTVAR table consists of various fields, each holding specific information or linking keys about IO Information About Account Creation Variant data available in SAP. These include RULENR (IO: Rule Number for Automatic Creation of an Account), XNEWACCOUNT (Checkbox), XNEWPARTNERACC (Checkbox)... 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. .
