1) Row row=vo.first();
I want to know how the meaning of line 1 is related to the meaning of line 5.Can anybody do the favour??
Thanks & Regards
In line 1, you are fetching the first row of the VO.
and in line 5, you are setting a value to the row's attribute, Pos_Flag. You can also do the same by using method row.setPos_Flag(TRUE);
