Generic program for calculating subtotals

Question

Dear All,
I have created a big sales ALV report for the company which collects the data from lot of tables.
Now the problem is, the report that I have created is Invoice-wise item-wise report. And every user and management do not want that item-wise report. As they need the same report like
1. Region-wise & Customer-wise, (e.g. North region, X customer) sales report.
2. Customer-wise, product-wise
3. Region-wise, customer-wise, product-wise.
4. Product-wise categorization
etc. and many more.
Although the report can be generated by putting the Subtotal (in ALV generated report) on the desired columns. But main problem with that is that Subtotal increase the number of rows drastically which does not look good.
To explain in detail:
Inv. No     Item      Material       Qty.     Value     Customer      Region
90001      10          A                10       1000         X                  10
90001      10          B                20       1500         X                  10
90002      10          A                50       6000         X                  10
In Basic ALV, I have only two rows. But when I do the subtotal  according to Regio-wise Customer-wise Material-wise,the number of rows will become 6.
But as per the given scenario, the number of rows should be only 2.
Region    Customer     Material     Qty     Value
10              X                   A             60      6000
10              X                   B             20      1500
So my requirement is how can I make such report in which user specify the columns against which he need the subtotals and rest all value & column related columns should add up WITHOUT ADDITION IN NUMBER OF ROWS.
If still you do not understand the problem then tell I will explain it more.
Kind Regards,
Vishal

Hi
U need to manage the ALV layout variant in your selection screen, in this way every user can decide which variant (so which detail) has to be used.
