Customization to go to the main table form

Go to the Main Table Form is a feature of Dynamics AX, which allows users to jump to the main record just by right-clicking on the field and selecting the Go to the Main Table Form option. It is based on table relations and is available for those controls whose data fields have foreign key relationships with other tables.
but,sometimes we are need to using (display/edit) methods to display on the gird.

such as  Form path :InventQurantineOrder) - > Grid - >purchId()(dsplay method)

1)OverLoad jumpref system reference method before

2)OverLoad jumpRef method after

 

X++ Code as below:

    FormRun         fr;
    FormDataSource  fds;
    Args            args = new Args();
    PurchId         purchId;
    PurchTable      CurPurchTable
;
    super();
    purchId         = InventQuarantineOrder.PurchId();
    CurPurchTable   = PurchTable::find(purchId);//current purchase order record

    args.name(formstr(PurchTable));
    fr = ClassFactory.formRunClass(args);
    fr.init();
    fr.run();
    fr.dataSource().findRecord(CurPurchTable);//jump reference for current PO record
    fr.detach();
