issue with 'F4IF_INT_TABLE_VALUE_REQUEST'

Hi, I am using this FM : 'F4IF_INT_TABLE_VALUE_REQUEST' in my screen program for F4 help.

when I select F4 and double click on value, it will return the valur into my screen field. then

I want to set the cursor at last of value in the same screen field. which is not happening.

It is going to set there where the previously cursor was placed in the same field.

Can anybody suggest how to do..

Thanks
