WSD_PURCHASING_ORG_STY 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 "Purchasing Organization Data" 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_WSD_PURCHASING_ORG_STY TYPE WSD_PURCHASING_ORG_STY.
The WSD_PURCHASING_ORG_STY table consists of various fields, each holding specific information or linking keys about Purchasing Organization Data data available in SAP. These include MANDT (Client), INFNR (Number of Purchasing Info Record), EKORG (Purchasing Organization), ESOKZ (Purchasing info record category)...
