Alv report with varying number of columns

Question

hi all,
I am new to abap. I am writing this to get a brief idea of what i wanted to do in system.
I have to do a report using alv.  The format of the report looks like this.
acc no     acc. name     amt_sum_april   amt_sum_may   amt_sum_june. ............. total_months
the colum amt_sum_ depends on user input period(month interval).
if the user selects 4 to 6 = 3 columns ,if the user selects 4 to 10 = 7 columns
so on.......
Anyone have idea how to do it, because in the
initial structure or itab, the number of columns depends on the user input.. i am stucking here ...
pls help.
thanks and regards
jose

Hi friend,
It's very complicated to do that, I'm sure there's a way to do it but I really don't know it. Once I had a similar requirement and I did something else that solved my problem without making a fussy complicated code. I added a colum MONTH or PERIOD (depending on your requirement) and then I make a subtotal by that column. So you need:
acc no acc. name amt_sum_april amt_sum_may amt_sum_june. ............. total_months
Now you would have:
acc no acc. name    month     amount
In the SORT table, in the sorting condition by MONTH you specify SUBTOTAL = 'X'. So the output will be:
acc no acc. name    month     amount
123123        John      2            100.00
123124        Paul      2            200.00
Month  2                                300.00
123123        John      3            300.00
123124        Paul      3            400.00
123125        Jane      3            100.00
Month  3                                 800.00
123123        John      4            123.54
Month   4                                123.54
Total                                      1223.54
You can change the subtotal text for a more adequate one (if you want). Also if you only need the subtotals you can specify in the layout that only those lines are to be output.
I hope I've helped, I you have any question let me know!
