COND_FIELD 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 "Condition Fields (such as Table Fields)" 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_COND_FIELD TYPE COND_FIELD.
The COND_FIELD table consists of various fields, each holding specific information or linking keys about Condition Fields (such as Table Fields) data available in SAP. These include FIELDNAME (Name of the condition field)... 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. .
