PAR01 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 "Data for generation of the DGI-SIJP diskette" 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_PAR01 TYPE PAR01.
The PAR01 table consists of various fields, each holding specific information or linking keys about Data for generation of the DGI-SIJP diskette data available in SAP. These include OBRAS (Welfare Fund), CONYU (Spouse/Partner), HIJOS (Number children according to Welfare Fund), ADHER (Welfare Fund next of kin)... 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. .
