Editlock expression

Hi All,

         Is there anyway i can open a series without using the function Getrow(),Currentrow() and Forecastfirstrow(). When i use these functions the locking mechanism automatically getting shifted depends on the strat date i selected in the worksheet. if i select sart date in the worksheet greater than forcast first row(minfore sales date) then the opened period is also getting shiftted accordingly, Please advice.

Thanks in advance,

VVM.
