E2PROFT 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 "Language-dependent descriptions of KB profile" 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_E2PROFT TYPE E2PROFT.
The E2PROFT table consists of various fields, each holding specific information or linking keys about Language-dependent descriptions of KB profile data available in SAP. These include PROFNAME (Knowledge-base profile for SCE), LANGUAGEID (Language key), DESCRIPT (Language-dependent description of knowledge base object)... 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. .
