How to execute code behind dosavenow() peoplecode using CI

Hi Team ,

I am facing one issue .I know that CI doesn't execute dosavenow() method.

I have created one application engine program where by using CI I am inserting data into component.

In a field change below delivered code is written .So when my program read dosavenow it doesn't do anything  but via online  when it read dosavenow it execute some set of saveedit event code where data gets updated into the database table based on the flag &NoUpdate = "Y";

&NoUpdate = "Y";             /*set the flag*/
&NOBIHDRSAVE = "Y";  /*set the flag*/
DoSaveNow();                /*database update*/
&NOBIHDRSAVE = "N";  /*reset the flag*/
&NoUpdate = "N";        /*reset the flag*/
