PARCTRLINT 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 "DD: Internal Check Parameter for Parallel Execution" 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_PARCTRLINT TYPE PARCTRLINT.
The PARCTRLINT table consists of various fields, each holding specific information or linking keys about DD: Internal Check Parameter for Parallel Execution data available in SAP. These include OBJNR (Total Number of Objects), COSTPEROBJ (Cost per Object in Milliseconds if no costtab), COSTTAB (), OFFSET (Offset of 1st Object to Set Task Low/High)... 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. .
