Data in BPS layout columns

Question

Hi,
   I have two data columns in my BPS layout called price and margin with one lead column material, the layout looks like this when it initially display:
   Material    Price   margin
      1          1.25
      2
      3
      4
The requirments is if user input date in the margin column and the price should be calculated by the following logic
     second  material price = (first price ) + (first margin) and so on.
     if we input margin column 0.50,0.40 0.30  for material 1,2,3,4 respectively, we will get the following price result:
    Material    Price   margin
      1          1.25    0.50
      2          1.75    0.40
      3          2.15    0.30
      4          2.45   
I am tried to use the excel formula for achieve this, but as much as I know the excel formula can not been saved when we configure the BPS layout,beside since the number of material display under different data selection criteria is vary, it's diffculty to hard code the formula in the excel.
Anybody have any suggestion how to do it?

Hi JW,
BPS is designed in a way that layouts and planning functions are completely independent of each other (otherwise you would have to build a layout for each function or something like that).
The data in the layout is sorted according to the lead column. So if you use FOREACH in FOX with the same characteristic, the data will be processed in the same order as the lead column.
Alternatively, you can do it with an exit function. All you need to do in an exit is copy XTH_DATA into an internal table and then use the SORT statement with the same sort key as the lead column.
  DATA:
    lr_aera     TYPE REF TO cl_sem_planarea_attributes,
    lr_t_data   TYPE REF TO data.
  FIELD-SYMBOLS:
    <lt_data>   TYPE STANDARD TABLE.
  CALL METHOD cl_sem_planarea_attributes=>get_instance
    EXPORTING
      i_area      = i_area
    RECEIVING
      er_instance = lr_area.
  CREATE DATA lr_t_data TYPE (lr_area->typename_t_data).
  ASSIGN lr_t_data->*   TO <lt_data>.
  <lt_data> = xth_data.
  sort <lt_data> by ...
your logic here
  xth_data = <lt_data>.
