VAR_IDENT 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 "Variable Identification: Structure Dialog" 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_VAR_IDENT TYPE VAR_IDENT.
The VAR_IDENT table consists of various fields, each holding specific information or linking keys about Variable Identification: Structure Dialog data available in SAP. These include CONT_FIELD1 (Container table field name), ID_TEXT1 (Description of the identification type), MAT_VARID1 (Var. Object Identification), CONT_FIELD2 (Container table 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. .
