PSMASTDATA1 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 "Master Data for Projects/WBS Elements in Report-Writer" 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_PSMASTDATA1 TYPE PSMASTDATA1.
The PSMASTDATA1 table consists of various fields, each holding specific information or linking keys about Master Data for Projects/WBS Elements in Report-Writer data available in SAP.
