PAR33 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 "SICORE file (Taxed persons Income Tax)" 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_PAR33 TYPE PAR33.
The PAR33 table consists of various fields, each holding specific information or linking keys about SICORE file (Taxed persons Income Tax) data available in SAP. These include RSSIC (Registered company name), DOSIC (Employee address), LOSIC (Residence locality), PRSIC (Provincial code for SICORE)... 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. .
