MDM_SELECT_PROPREFIX 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 "Selection Conditions (Copy of MDM_SELECT)" 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_MDM_SELECT_PROPREFIX TYPE MDM_SELECT_PROPREFIX.
The MDM_SELECT_PROPREFIX table consists of various fields, each holding specific information or linking keys about Selection Conditions (Copy of MDM_SELECT) data available in SAP. These include FIELD (Logical Field Name), SIGN (Selection Operator SIGN (Copy of MDM_SIGN)), OPTION (Selection Operator OPTION (Copy of MDM_OPTION)), LOW (Selection Criteria: From-Value)... 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. .
