EWCTYPE 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 "Cat. Description of a Container Element" 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_EWCTYPE TYPE EWCTYPE.
The EWCTYPE table consists of various fields, each holding specific information or linking keys about Cat. Description of a Container Element data available in SAP. These include TABELEM (Multiline element), REFOBJTYPE (Reference obj. type), REFSTRUCT (Reference table), REFFIELD (Reference 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. .
