EDESK_LONGTEXT 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 "Engineering Desktop" 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_EDESK_LONGTEXT TYPE EDESK_LONGTEXT.
The EDESK_LONGTEXT table consists of various fields, each holding specific information or linking keys about Engineering Desktop data available in SAP. These include DELETEVALUE (Deletion Indicator), LANGUAGE (Language Key), LANGUAGE_ISO (2-Character SAP Language Code), TEXTLINE (Text Line)... 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. .
