COUP_SORT_FIELDS 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 "Possible Sort Fields Collective Conversion of Planned Orders" 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_COUP_SORT_FIELDS TYPE COUP_SORT_FIELDS.
The COUP_SORT_FIELDS table consists of various fields, each holding specific information or linking keys about Possible Sort Fields Collective Conversion of Planned Orders data available in SAP. These include PWWRK (Production plant in planned order), PERTR (Planned opening date in planned order), PSTTR (Order start date in planned order), PEDTR (Order finish date in the planned order)...
