ALM_DOE_DATE 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 "Date on variant selection" 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_ALM_DOE_DATE TYPE ALM_DOE_DATE.
The ALM_DOE_DATE table consists of various fields, each holding specific information or linking keys about Date on variant selection data available in SAP. These include SELECTION_HIGH (Valid-to date), PATTERN_FLAG (Version Number Component), SEL_OPTION (ABAP: Selection option (EQ/BT/CP/...)), SIGN (ABAP: ID: I/E (include/exclude values))... 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. .
