How to add dynamic prompt table without adding a hidden field DERIVED EDITTABLE on the page..?

Hello PSFT Community Members,

I am trying to add dynamic prompt table without adding DERVIED EDITTABLE field on the page but does not work. According to peoplebook(Link below), if we use SetEdittable method with ExecuteEdits() then we don't need to add the hidden field on the page, but however it doesn't seems to be working

Below is a snip of my code

&RS_DST = GetLevel0()(1).GetRowset(Scroll.PAY_MISC_DST);
   For &S = 1 To &RS_DST.ActiveRowCount
      &ROW_DST = &RS_DST.GetRow(&S);
